Paper Abstract

FESTA has been developing short pulse X-ray generation technologies using Laser-Compton scattering. Two years ago, X-ray generation with a 90-degree collision configuration was achieved using a photocathode as the electron source and a 100fs Ti:sapphire laser as the photon source. Electron and laser light pulses were synchronized so that the fluctuation of X-ray intensity was 25% (rms). In the next stage, the x-ray generation system is being modified for use in practical applications. The electron energy has been raised to 40 MeV to increase to X-ray photon energy. Laser power will be increased to 0.5 J/pulse with a 100Hz repetition rate. The laser gain medium has been changed to Yb:S-FAP which is pumped by laser diodes. The synchronization system will be further modified to increase its stability. These technologies will be used to generate 15 -to 30 keV X-ray pulses with a stable peak-to-peak intensity for use in several applications.
