Laboratory of accelerator facilityhttp://danp.sinp.msu.ru/LAA/Laa.htmLaboratory of accelerator facility
The Laboratory of accelerator facility (LAF) was organized in 1995 on the base of three charged particles accelerators: 120-cm cyclotron P-7, electrostatic (Van de Graaf) generator accelerator EG-8 and cascade Cockroft-Walton accelerator KG-500. All these accelerators were designed, developed and put into operation in the late 1950s and the early 1960s. Scientists of a number of SINP departments active use accelerators in their research in the field of fundamental physics, applied physics and allied sciences along with learning goals during the eduction of the students of MSU Physics Physics Department.
From the very beginning of the Laboratory it's head is PhD. Andrey Spassky.
Description of chrged particles accelerators:
I. 120 cm cyclotron (of P7 type) is intended for acceleration of light ions with А = 1-4 up to energy of 7,8 MeV/nucleon:
protons up to 5÷8 MeV,
deuterons up to 10÷16 MeV,
Helium-3 up to 15÷24 MeV,
alfa-particles up to 20÷30 MeV.
Beam current is up to 60 micro ampere, ejected beam current is up to 10 micro ampere.
Protons and alfa-particles are mainly accelerated particles, deuterons and Helium-3 are accelerated from time to time.
The accelerator is used for scientific research in the field of fundamental nuclear physics of medium energy and for different tasks in the applied and allied areas, for instance:
1. Backward scattering methods are used for elemental analysis of the near-surface layers of the materials.
2. Nuclear reactions are used for non-destructive analysis of some elements' content in biological samples.
3. By means of fast particles produced during nuclear reactions instruments based on silicon semiconductor detectors are tested and calibrated.
4. Short-lived isotopes are used for medical and other purposes.
Protons and alfa-particles backward scattering methods is used for profiling of oxygen content in alloy steels, for studies of structural materials nitriding, other purposes.
Products of the reactions occured in thin biological and agrochemical samples and selectively separated by means of specific nuclear reactions. It is possible to determine content of boron, carbon, nitrogen, oxugen, sulphur and other light elements' isotopes within the accuracy of several percents.
Fast and light reaction products turned out to be a convenient tool for calibration of complex instruments based on semiconductor cilicon detectors, in particular, used for space-physics reseacrh. By means of protons produced during reactions of 3Не++ ions it is succeeded to test instruments consisted of a number of detectors with total thickness up to 8 mm.
Studies of production of radioactive isotops of thallium, astatine, used for medical purposes, cobalt-59 and other elements are caaried by means of ejected beam of 4Не++ ions.
II. Accelerator facility of electrostatic (Van de Graaf) generator (EG-8) is intended for production of positively charged protons, alfa-particlesm nitrogen ions, etc. ejected into experimental hall with energy up to 4 MeV/charge which is the maximum theoretically possible for this facility and the maximum current of I = 10 micro ampere. In practice at this accelerator the maximum energy for the protons achived 3 MeV.
Besides the experiments with positively charged particles (protons and alfa-particles) the accelerator was used for acceleration of the electrons and charged microparticles (macrones or dust particles) in order to study their influence on the spacecrafts' surface.
In 1980s the accelerator was essentially upgraded by DSc. Alexander Almazov, who worked as a Senior Reearcher of the Department of atomic nucleus physics from 1980 till 1985.
After full reconstruction of the electrostatic accelerator under his management it became one of the best faciclities in the USSR, conforming to international standards. In particular, tape station of the accelerator was replaced with induction one designed by Alexander Almazov. A new axially-symmetrical septated acceleration tube was installed, accelerator column was also essentially reconstructed. A new high-reliable resistive high voltage divider also designed by Almazov was isntalled in it. System of beam energy stabilization was designed and manufactured.
Currently the accelerator is actively used for the studies of metallic, semiconductor and dielectric materials in poly- and monocrystal phases by means of ion-beam analysis.
III. An accelerator KG-500 is a high-voltage Cockroft-Walton cascade generator with air isolation which is intended for acceleration of positively charges ions in electrostatic field.
Basic parameters of ions acceleration (for hydrogen) are the following:
a) maximum energy - 500 keV;
b) energy stability - 0,1%;
c) energy range - 50-500 keV;
d) direct beam current (at the input of magnetic analyzer) - 1 mA;
e) direct beam current density - 25 mA/mm2;
f) monoatomic ions current in a beam, deflected for 90o, - 0,2 mA.
Vertically directed ion beam is turned in horizontal plane by two magnetic analyzers and ejected for operation in five vacuum experimental chambers and plant MEIS (Medium Energy Ion Scattering) with native energy resolution of ~ 10-3 E0 .
IV. Horizontal electrostatic van de Graaf accelerator (AN-2500) with maximum potentials difference of 2,5 MV manufactured by HVEE (Netherlands) was put into operation in 2009. The accelerator was purchased basing on the Agreement between the Center of Material Science of Gronningen province (Netherlands) and SINP MSU as gratuitous transfer for scientific research and educational purposes.
Technical parameters of the accelerator are the following:
- energy of accelerated particles - up to 2,5 MeV (during the recent years of the acelerator's operation in Gronningen it did not exceed 1,5 MeV);
- types of accelerated particles: positive ions of hydrogen and helium;
- accelrating tube and conductor are situated in a horizontal steel boiler 3 meters in length and 1,5 m in diameter under pressure of 20 atm. of isolating gas.
Accelerator's design provides absence of negative influence to the environment due to radiation monitoring and protection, electromagnetic shielding, зкotection from line noise. More

Department for Nuclear Researchhttp://www.msu.dubna.ruDepartment for Nuclear Research
A branch of SINP MSU was organized in 1961 as a training facility for personnel training for the Joint Institute for Nuclear Research (JINR) in Dubna. In 2011 the branch was re-organized into the Department for Nuclear Research (DNR).
The branch was founded by the MSU Professors: the first JINR Director Dmitry Blokhintsev, Vladimir Veksler and the Academician Sergey Vernov, who in 1960 became a Director of SINP and a Head of the Nuclear Physics Division of the MSU Physics Department. MSU Rector, Academician Ivan Petrovsky, the Dean of the Physics Department, Professor Vasily Fursov, SINP Director, Academician Dmitry Skobeltsyn also took active part in the development of the branch. Yuri Lobanov was the first Director of the branch, after him Ernast Uruzakov (1972-1975), Anatoly ABrosimov (19750-1982), Anatoly Kulikov (1982-1994) leaded the branch. From 1994 till present DNR is leaded by Tatiana Tetereva.
At varying times Academicians Vladimir Veksler, Vladimir Kadyshevsky, Anatoly Logunov, Bruno Pontekorvo, Ilya Frank, Corresponding Members of the Academy of Sciences Dmitry Blokhintsev, Mikhail Meshcheryakov, Fedor Shpiro and others gave lectures in the Branch. Many leading scientists of JINR participated in the training activity (both in the lectures and in practical studies). A number of monographs and study guides are published basing on the lectures given in the Branch. Among them are the following: D. Blokhintsev "Principal problems of quantum mechanics", V.Babikov "Phase functions method in quantum mechanics", S.Bilenky "Introduction to the Feynman diagram technology" and "Lectures on physics of neutrino and lepton-nucleon processes", G.Kopylov "Basics of resonance kinematics" and "Theoretical training on nuclear and atomic physics", V.Solovyov "Theory of complicated nuclei" and "Theory of the atomic nucleus: nuclear models".
The number of the graduates of the Branch is over one thousand taking into account the students, post-graduates of MSU and other institutes. All of them continued their activity in the leading Russian research institutes: JINR, SINP, Lebedev Physical Institute, Institute for Nuclear Research, Institute of Experimental Physics, etc. Many graduates became leading specialists of JINR, heads of educational and scientific centers both in Russian Federation and former republics of the USSR. The Deans, Pro-rectors, Directors of the Institutes and even Presidents of the Academies are among them. Currently the students from Tula, Kostroma, Tver, Nizhny Novgorod, Krasnoyarsk, Irkutsk, Ekaterinburg and other Russian towns study at the Branch according to the individual plans of the MSU Chairs programs.
Besides the basic chairs other chairs of the Nuclear Department also collaborate with the Branch. First of all, among them are the Chair of the Atomic Nuclei Physics and Quantum Theory of Collisions and the Chair of Quantum Statistics and Field Theory. Although these Chairs were always located in Moscow, part of the students studied in Dubna according to individual plans. During a number of years Academician Nikolay Bogolyubov was simultaneously the Head of the Chair of Quantum Statistics and Field Theory and the Director of JINR. He made significant contribution to the development of the Branch, as SINP Director (in 1980-1991) Igor Teplov, SINP Deputy Director, Professor Leonid Kornienko, Deputy Head of the Department of Nuclear Physics Goryaga, and Professor Tyapkin, who in 1986-2003 was a Head of the Chair of Elementary Particles.
Training of the students in Dubna began in October 1961. The education process in DNR is kept with some twists from the very beginning. At the beginning of the 7th semester students come to Dubna and attend specific courses given by the leading scientists of JINR, and also do special practical training in DNR and scientific laboratories of JINR. Simultaneously they come to know the research problems of different scientific groups. From the 8th semester they become full members of the scientific groups of JINR laboratories, doing educational and practical training and executing student essays and diploma thesis under the leadership of the leading scientists. So the Branch for the students joint education in MSU and scientific research in one of the biggest research centers in the world - JINR.
Currently two MSU Chairs work on the basis of DNR: the Chair of Elementary Particles Physics founded simultaneously with the Branch (the Head is scientific leader of JINR Academician Vladimir Kadyshevsky) and the Chair of Neutronography organized in 2000 (the Head is the Directr of B.P.Konstantinov Petersburg Institute of Nuclear Physics Corresponding Member of RAS Viktor Aksenov).
Besides the Chairs there is also MSU Interdepartmental Center (IDC) "Mateial structure and new materials" founded in 1998 and operated on DNR base. IDC organization is a natural way of development of a system for personnel training not only in the field of physics, but also mathematics, chemistry, etc.
DNR actively participate in the scientific research in the directions of its basic Chairs activity wihin the frames two SINP scientific topics. PhD. Sergey Trusov is a Head of "The studies of mesons, deutrons and pion bound states production during proton-nuclear interactions" within the frames of the direction "High energy physics", and the Head of the Chair of Neutronography Viktor Aksenov is a Head of the studies in "Neutronography of the surfaces and layered structures".
The basic purpose of the educational activity of DNR is training of the students of the 4th year (Physics Department MSU) and supporing of their practical work. The following facilities are organized in DNR for this purpose:
- several exercises of a special practical training for the 4th year students are working and permanently improved. In particular, an exercise within the program of the Chair of Neutronography is operated at the advanced equipment - Raman scanning con-focal microscope SOLAR TII;
- a number of new educational exercises within the program of the Chair of Physics of Elementary Particles introduce students to the methods of the development of system for trigger signals producing in physical experiment. These exercises simulate the elementary electronical items of any physical equipment used in the field of high-energy physics. Students learn modern methods of data processing basing on the systems operated at the experimental equipment of the leading scientific centers;
- videoconferencing facilities are used for interactive remote dialog with specialists from different research centers. In order to keep hand in English the students of the senior years have trainings in the language laboratory and during extracurricular activities with students reports in taken topics.
One more DNR purpose is to provide MSU adequate participation in the educational activity in Dubna. For this end starting from 2002 a specific admission was organized to the basic DNR Chairs. From the 1st year of education the students have additional training within the frames of the Chairs' specialization. Starting from 1994 DNR takes part in mock exams to the Physics Department and off-site schook olimpiades.
Currently there are scientific schools for the students, post-graduates and young scientists in the field of neutronography and educational and industrial R&D internships for the students of the Physics and other MSU departments organized on the basis of DNR. There the students come to know the advanced experimental facilities of JINR and have laboratory training developed by the staff of the DNR Chairs and JINR on them.
Regularly the Chair of the Accelerators High-Energy Physics organizes practical training in "medical physics" for the students of the Physics Department. It is popular not only among the students of the Chairs of Biophysics and General Nuclear Physics, but also among the students of the Biological Department of MSU and other universties. Besides, DNR takes part in organizing practical training for the students of the Department of Fundamental Medicine basing on the medical unit of JINR.
It is necessary to note, that DNR get grants from the following Russian and international organizations and programs:
- RF Ministry of education and science (collaboration program with CERN - Dirac experiment);
- German Government foundation FFE (travel grant for the visits to the Research Center in Julich);
- LTP JINR within the frames of the program "Votruba-Blokhintsev" (support for collaboration between the Institutes of the Chezch Republic and JINR).
DNR carries out its R&D activity in collaboration with JINR. DNR scientists also cooperate with the Kostroma, Tula, Irkutsk, Belgorod, Saratov, Samara universities in the development of many scientific problems.
So a system of permanent education (senior school - MSU - academical science) is organized on DNR basis. In fact, DNR is MSU educational and scientific center in Dubna. More

Laboratory of nuclear and spectroscopic methodshttp://dnsm.sinp.msu.ru/Laboratory of nuclear and spectroscopic methods
The Laboratory of nuclear and spectroscopic methods (LNSM) was founded in 2013 from the Department of nuclear and spectroscopic methods which in turn originated from the Labratory of nuclear spectroscopy. The Head of the Laboratory is PhD. Irina Romashkina.
The studies of electon-nuclear interactions in the solid state by means of three methods: Mossbauer effect method, method of perturbated angular correlations of nuclear radiation and method of low-temperature nuclear orientation - provided a basis for the Laboratory's activity. These methods were developed by one of the founders of Mossbauer spectroscopy in the Soviet Union, the Head of the Laboratory in 1951-1986 Vladimir SHpinel.
Currently the scientists of the Laboratory study complicated magnetic systems by means of Mossbauer nuclei as probes, which provide information about the structure and properties of crystals at the local level.
Phenomenon of temporal self-organizing in the crystals under influence of electric shock, gamma-emission or external pressure were studied by means of Mossbauer effect method. A new approach to the problem of collective excitation of Mossbauer nuclei is developed.
A unique remote access Mossbauer spectrometer is developed and manufactured.
Magnetic structure of metallic systems with competing change interactions (magnetic iron allys with transition metals, intermetallides of rare earth elements and uranium) are studied by means of Mossbauer effect. New information about the influence of change interactions on the type of magnetic ordering and on the phase changes and new data on magneto-elestic interactions in the binary iron alloy were obtained.
Development of the method of perturbated angular correlations (PAC) provided a basis for the studies of local electronical and magnetic properties of the substances under conditions of extremal compression. The scientists of the Laboratory in cooperation with colleagues from the Institute of High-Pressure Physics RAS, Joint Institute of Nuclear Research and Institute of Physics of M. Curie-Sklodowska University (20-031 Lublin, Poland) have shown that PAC method can be used for determination of change of ytterbium ions valency in the intermetallic compounds depending on pressure and for studies of quarupole phase changes in the compaunds with cubic structure.
One of the directions of the Laboratory's activity is studies of the physical basis of the operation of soft X-ray and gamma-detectors based on superconductive tunneling transitions, which need low temperature. A computerized instruments complex for registration of current-voltage characteristics of tunneling transitions, signal shape and amplitude spectra produced during radiation quants absorption within wide temperature range from helium to milli-degrees was developed. It was found that energy resolution of niobium-based detectors is better, than up-to-date semiconductor detectors. Investigations of tantalum-based detectors was started.
A group of theorists consisted of Leonid Blokhintsev, Yuri Orlov, Dmitry Savin is specialized in application of analytical methods for the theory of nuclear reactions and the theory of several particles nuclear systems. Astrophysical nuclear reactions are under investigation. Special attention is paid to the sequent and effective recording of Coulomb effects which significantly change the properties of nuclear processes amplitudes and their behaviour at low energy.
Another group of theorists consisted of Grigory Koreman, Vladimir Popov, Sergey Yudin is specialized in the exotic atoms theory, including muons and hadrons (pions, kaons, antiprotons). Properties of these atoms and processes with their participation are discussed. Specific attention is paid to such processes as QCD performance in hadron atoms, Lamb shift in muon atoms, etc., which influence significantly on the possibility of carrying out experiments on precised measurements of muon and hadron atoms characteristics, which in turn is associated with the problems of fundamental symmetry and interaction.
During the last five years the scientists under the leadership of Grigory Korenman developed a model of collisional transitions between the sub-levels of super-fine structure of anti-proton helium atom, calculated collisional transitions and spread of M1-transitions, analyzed kinetics of the transitions between the conditions of super-fine structure in anti-proton helium basing on the method of generalized quantum kinetics equation, which allows simultaneous taking into account influence of collisional processes and of external micro-wave emission. Cross-sections of elastic scattering, Stark and Coulomb transitions of the excited muon and pion hydrogen atoms were calculated, dynamics of the lightest hadron atoms in the medium at low temperature was analyzed. The projects on RFBR grants and joint RFBR-Austrian scientific foundation were executed.
The scientists of the Laboratory cooperate with colleagues from the Joint Institute of Nuclear Research (Dubna, Russia), Institute of High-Pressure Physics RAS (Troitsk, Russia), Kotelnikov Institute of Radioelectronics RAS (Moscow, Russia), Texas A&M University (Texas, USA), Istituto Nazionale di Fisica Nucleare (Fraskati, Italy), Laboratore Nazionale del Sud (Katanya, Italy), Institute of Nuclear Physics (Tashkent, Uzbekistan), Institute of Physics of M. Curie-Sklodowska University (Lyublin, Poland), Stefan Meyer Institute for Subatomic Physics, Austrian Academy of Science (Vienna, Austria), University of Tokyo (Tokyo, Japan), Japan Institute for Physical and Chemical Research (RIKEN), Universita di Brescia (Italy).
A conference "Mossbauer Spectroscopy and Its Applications" is organized starting from 1985. The latest ICMSA-12 happened in 2012. More
