Abstract: Inverse Compton scattering by relativistic electrons off intense laser pulses is becoming an increasingly prevalent compact source of tunable radiation in X-ray spectral range. The brightness of typical Compton sources, unfortunately, remains small compared to large scale facilities. The Compton brightness can be enhanced significantly via a shallow angle scattering geometry and superradiant emission from a density modulated electron beam, which are shown to be complementary methods via the use of inverse free electron laser microbunching. Furthermore, we will discuss our experimental efforts towards the observation of superradiant Compton scattering at the UCLA Pegasus laboratory, including diagnostics of strongly compressed electron bunches -such as longitudinal phase space tomography, electro-optic sampling, and THz streaking- and the recent demonstration of shallow angle Compton scattering.
