On the basis of laboratory opens SINP MSU electron accelerators

A working prototype of an electron linear accelerator at the energy of 10 MeV

Based SINP opens laboratory that will develop electron accelerators and will participate in their small-scale production. This project is implemented in a public-private partnership in accordance with the Decree 217 of the Government of the Russian Federation. In the creation of the laboratory of electron accelerators MSU attended MSU University and the private company "Skantronik Systems".

"Scope of electron accelerators is very wide, they are used in medicine, industry processes, in installations for sterilization in the inspection and Inspection complexes in the inspection. The development of accelerators for this purpose will be the priority of the laboratory of electron accelerators MSU ", — the doctor of physical and mathematical sciences, professor, head of the Laboratory Division of electron beams of electromagnetic processes and interactions of atomic nuclei SINP Basil Shvedunov. 

He further said that the main part of the new laboratory will include scientists and engineers laboratory electron beams SINP with experience in the development of electron accelerators of various types. The average age of employees — about 35 years. Furthermore, in the laboratory of electron accelerators MSU will come from other organizations, engineers and designers, who have great experience in developing electric vacuum equipment.

Start own research and development in the field of electron accelerators in the SINP laid in 1983, the project continuous electron accelerator — microtron energy 175 MeV and an average beam current of 100 pA. The accelerator was designed for scientific research — the study of the mechanism of interaction of electromagnetic radiation with atomic nuclei.

In 1992, the Institute of Nuclear Physics of Moscow State University, a laboratory of electron beams, which are continuing to work with electron accelerators. It has developed a number of linear electron accelerators continuous with energy from 0.5 to 2.1 MeV and beam power up to 60 kW. In collaboration with scientists from other institutions were created microtron pulse of energy 35, 55 and 70 MeV. Feature split mirco-energy 35 and 70 MeV is the extensive use of rare earth magnetic material when creating their magnetic systems.

The turning point for the laboratory electron beams SINP was in 2003, when it was launched in conjunction with the Federal State Unitary Enterprise "SPE" Tory "the development of a powerful electron accelerator for sterilization and process technology for energy 10 MeV. Working prototype of this accelerator, launched into operation in 2007, joins Park SINP accelerators and increased the number of performed research and application.

First established in the production of the accelerator in the creation of which was attended by employees of the laboratory of electron beams SINP, was a linear accelerator for radiography. From April 2012, the accelerator operates in one of Rosatom and is used to control the weld elements of nuclear reactors. The accelerator has a number of advantages in comparison with domestic and foreign counterparts. His energy and the dose may vary in a wide range of 3 — 8 MeV and 1-10 Gy / min, respectively. Using the klystron as a microwave source and a solid state modulator for its power considerably increase the life of the accelerator. Thanks to the sealed-off structure of the accelerating structure and the modern system of control and management of the operating organization is not required include specialists in the accelerator. The accelerator has a small size and weight, and thus includes an effective radiation protection, reducing the level of stray radiation 10,000 times.

In 2012, together with the private company "Skantronik Systems" was held over the creation and acceptance of the accelerator with poimpulsnym switching energy for the inspection and of the inspection of the complex. During the tests, due to the high stability of the beam energy, as well as the features of the system of detection and imaging specialists private company demonstrated ability to identify materials with a resolution of atomic number close to unity. Is currently under inspection and installation of the inspection of the complex on the border of the Russian Federation in the Far East.

"It was a successful cooperation with the company" Skantronik Systems "became the basis for the decision to establish a joint venture" Laboratory of electron accelerators MSU, "- said the scientist SINP Basil Shvedunov.

Currently, the SINP has a number of new developments that are in varying degrees of implementation. For example, a compact linear accelerator continuous energy of 1 MeV and a beam power of 25 kW, the electron accelerator for intraoperative radiation therapy, created in conjunction with the Polytechnic University of Catalonia, the project laser-electron generator of monochromatic X-rays with tunable energy — together with the LPI.

"We hope that the cooperation with the" Skantronik Systems "in the new laboratory of electron accelerators MSU will help the successful completion of these developments and their implementation in practice", — said Vasily Shvedunov.
