Laser Compton scattering experiments were carried out at the Iadho Accelerator Center (IAC)using the 5-44 MeV LINAC. LCS X-rays were generated using a 5 ns electron beam interacting with a 100 MW, 7 ns laser and a 50 ps electron beam colliding with a 4 GW, 250 ps laser. X-rays resulting from the approximate head-on collision of relativistic electrons with a high peak power Nd:YAG laser fundamental, second and fourth harmonic lines were generated respectively. The LCS x-ray peak widths (FWHM) were measured as a function of the electron beam energy-spread and LCS spatial scans across the x-ray cone were also carried out using x-ray generated from the electron beam interaction with the laser second harmonic line. LCS angular measurements enabled us to determine the electron beam parameters in a single experiment. LCS x-rays were also used for XRF experiments and x-ray transmission/absorption measurements in Al, Nd, Pb and Bi foils of different thicknesses. Our experiments showed the dual applications of LCS as a useful x-ray source with application to biomedical imaging, hybrid k-edge densitometry and material science as well as a non-destructive electron beam monitor.
