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 1013 phot/s.
INTRODUCTION
The paper is one out of regular progress reports of the
supported by SfP NATO Grant #977982 project of
NESTOR (New-generation Electron STOrage Ring) X-ray
generator based on Compton scattering of an intense laser
beam on electron beam with low energy circulating in a
storage ring [1-5]. Technical design report of the facility has
been issued last year and design and development of the
main facility systems has been continued during the year. By
now bending magnets of the lattice and pilot specimens of
quadrupole magnets were manufactured, new scheme of
injection was designed, the first items of power supply
system and control system were produced and are under
examination. Elements of vacuum system are under design.
Construction of facility foundation was finished by the end
of May, 2005 and preparation of the whole operation room
will be finished by the end of 2005 year.
MAIN NESTOR FACILITY
PARAMETERS
Radiation intensity and brightness are the main
characteristics of any light source. Based on the strategy of
maximum X-ray intensity with feasible parameters of
technological systems the main NESTOR facility
parameters were worked out (Table 1).

NESTOR ALLOCATION AND
CONSTRUCTION PROGRESS
NESTOR X-ray source is constructed on the base of N-
100 electron storage ring and is located in a building of
300 MeV linear accelerator complex. Such decision
makes the total cost of the project much cheaper for the
reasons of existed infrastructure using and absence of
building construction costs. Layout of the NESTOR
facility is presented in Fig. 1. For new equipment
allocation an old radiation shelter has been broken down
and new one is going to be build. Old accelerators
sections and N-100 storage ring were dismounted and
new accelerator section, injection channel and magnetic
system of the storage ring along with a laser system will
be assembled as it is shown in the figure.
Under design and construction of the NESTOR ring
foundation the total mass of equipment (of about 50
tones), geometric parameters and the strict requirements
to installation errors of magnetic elements of the ring
( 75 p) were taken into consideration.Contributed to 27th International Free Electron Laser Conference (FEL 2005),
