And a rechargeable electrostatic generator EGP-10K, which accelerates protons and deuterons with the selected precision energy step in the range of 2 - 8 MeV. To obtain information about the parameters of the beam, detectors are used, which differ not only in the physical principle of operation, but also in the degree of complexity, and the method of data processing for their further use in automated accelerator control systems. The second stage of this research is devoted to the choice of the method of control of the parameters of charged particle beams, which are most suitable for non-destructive diagnostics of accelerator beams. The analysis conducted at this stage, based on a review of the various approaches used today to control the parameters of charged particle beams obtained in the first stage, showed that for recharging electrostatic generator EGP-10K will be optimal to use radiation-resistant scanners. laid metal microdetectors (MMD). A beam of charged particles or photons passing through the strips causes a VEE, generating an additional charge that is integrated by a highly sensitive charge integrator connected to the strip. The main role in the phenomenon of WEE is played by a thin near-surface layer of metal <50 nm, which makes it possible to create ultra-thin detectors. And in the case of classical and isochronous cyclotrons, the control problem can be solved using a beam position sensor, in which the amplification of the flow of secondary emission electr Product Description popup.authors Borzakovskyj Andriy Ye Vojter Volodymyr P Gorpinich Olga K Doronin Mykhajlo I Kisurin Kostjantyn K Karlyshev Jurij Ya Kovalyov Olexandr M Kuts Volodymyr I Maznyj Ivan O Makovskyj Mykhajlo V Mykhajlov Leonid V Ostashko Volodymyr V Roznjuk Jurij S Sokolov Olexandr M popup.nrat_date 2021-11-09 Close
