Progress in Development of Kharkov X-Ray Generator Nestor

The sources of the X-rays based on Compton scattering of intense Nd:YAG laser beam on electron beam circulating in a storage ring with beam energy 43-225 MeV is under construction in NSC KIPT. In the paper the progress in development and construction of Kharkov X-ray generator NESTOR is presented. The current status of the main facility system design and development are described. New scheme and main parameters of injection system are presented. The status of power supply system and control system is described. The facility is going to be in operation in the middle of 2007 and generated X-rays flux is expected to be of about 10{sup 13} phot/s

The start of X-ray generator NESTOR comissioning

The first results of the NESTOR facility commissioning are presented. 60 MeV electron linac injector has been tested and the first electron beam with project parameters was registered at the screen monitors. Electron beam was passed through the transportation channel and injection system. The beamh of electrons was observed and controlled in the screen monitors in the expected range.Перші результати вводу в експлуатацію генератора НЕСТОР представлені. Інжектор-лінійний прискорювач на 60 МеВ електронів був випробуван, та перший пучок із проектними параметрами було зареєстровано на екранах моніторів. Електронний пучок проведено крізь канал транспортування та системи вводу в вакуумну камеру накопичувача. Пучок електронів спостерігається і контролюється на екранах моніторів в очікуваному діапазоні.Представлены первые результаты ввода в эксплуатацию генератора НЕСТОР.

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
