X-ray generator based on Compton scattering

摘要

Nowadays, the sources of the X-rays based on a storage ring with low beam energy and Compton scattering of intense laser beam are under development in several laboratories. In the paper the state-of-art in development and construction of cooperative project of a Kharkov advanced X-ray source NESTOR based on electron storage ring with beam energy 43-225 MeV and Nd:YAG laser are described. The layout of the facility is presented and latest results are described. The designed lattice includes 4 dipole magnets with combined focusing functions, 20 quadrupole magnets and 19 sextupoles with correcting components of magnetic field. At present, a set of quadrupole magnet is under manufacture and bending magnet reconstruction is going on. The main parameters of developed vacuum system providing residual gas pressure in the storage ring vacuum chamber up to 10~(-9) Torr are presented. The basic parameters of the X-ray source laser and injection systems are presented. The facility is going to be in operation from the middle of 2006 and generated X-ray flux is expected to be of about 10~(13) phot/s.
