Abstract

We performed an experiment of high brightness gamma(γ)-rays production through laser-electron(e^-) collisions using an insertion device with a short focal length of laser optics. Number of generated γ-rays with the bunch length of 26 psec (r.m.s) was 0.92 × 10⁵/bunch, thus leading to brightness 2.5 × 10¹⁷ / (mm² · mrad² · 0.1%band-width·sec). Quantitative considerations on the basis of numerical model permitted to elucidate how characteristics of e^- and laser beam influence collision mechanisms.
