Description
Laser-driven Compton sources have emerged as a promising compact method for producing X-ray radiation with femtosecond pulse duration. They offer adjustable energy and bandwidth that can be controlled by the parameters of the electron beam and the colliding laser pulse. In addition, the transverse source size can be as small as a micrometer, making such sources of interest for high resolution X-ray radiography. At LOA, the LAPLACE-HC$*$ project aims to use a laser-plasma accelerator (LPA)$**$ to drive an Inverse Compton Scattering Source (ICS)$***$, producing tunable X-ray pulses in the 10-100’s KeV range and running at 100 Hz. LAPLACE-HC has recently completed the commissioning of its first phase and with a future upgrade coming, the laser energy should reach the Joule level, in 25 fs laser pulses, allowing the production of 100’s of MeV electron beams at 100 Hz. In this work, we present numerical simulations of the performance of the future ICS source using LAPLACE-HC laser beam parameters.
