Status of Kharkov X-ray Generator based on Compton Scattering NESTOR

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 is described. The layout of the facility is presented and main results and constructing timetable are described. The designed lattice includes 4 dipole magnets with combined focusing functions, 20 quadrupole magnets and 19 sextupoles with octupole component of magnetic field. At the present time a set of quadrupole magnet is under manufacturing 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 along with testing measurement at NSC KIPT vacuum bench. The facility is going to be in operation in the middle of 2006 and generated X-rays flux is expexted to be of about 1013 phot/s

Status of NESTOR

NSC KIPT proposed to construct a new X-ray and soft UV source NESTOR with a 40 - 225 MeV electron storage ring in Kharkov. NESTOR is a new type radiation source on the base of Compton scattering and a storage ring. Electrons are injected in the storage ring at 100 MeV and ramped up to final energy of 225 MeV. So, using interaction angle 10 Deg and 150 Deg, the facility covers operation energy range of radiation from soft UV trough synchrotron radiation from bending magnets up to hard X-ray radiation through Compton scattering (.apprx.1 eV .apprx.1 MeV). It is supposed that stored electron beam current will be of about 200 mA. Along with use of Nd:Yag laser of 10 W av. power which was developed by High-Q laser firm and optical resonator with accumulation gain of about 1000 it allows to provide X-ray radiation flux up to 1011 phot/s. NESTOR is the cooperative facility and its development is supported by Ukrainian government and NATO SfP project #977982. It is supposed that NESTOR will be in operation by mid-2007 yr. The status of the project and main facility systems are described in the report
