The main parameters of Kharkov electron storage ring N-100 with a beam ener
gy range from 70 to 150 MeV are presented. The main results that were obtai
ned in experimental researches are briefly described. The future of the N-1
00 upgrade to the development of the X-ray generator based on Compton back-
scattering are presented. The electron beam energy range will be extended u
p to 250 MeV and the circumference of the storage ring will be 13.72 m. The
lattice, parameters of the electron beam and the Compton back-scattering p
hotons flux are described. (C) 2001 Elsevier Science B.V. All rights reserv
