Applicability was studied and previous estimation was done of power X-ray b
eams generation by backward Compton scattering of a laser photon beam on a
cooled down electron beam. The few MeV electron beam circulating in a compa
ct storage ring can be cooled down by interaction of that beam with powerfu
l laser radiation of micrometer wavelength to achieve normalized emittance
of 10(-7) m. A tunable X-ray source of photons of energy ranging from few k
eV up to a hundred keV could result from the interaction of the laser beam
with a dense electron beam. (C) 2000 Published by Elsevier Science B.V. All
