Description

Status and capabilities of nonlinear Inverse Compton Scattering (ICS) experiments at the Brookhaven National Laboratory (BNL) Accelerator Test Facility (ATF), utilizing a 9.3 µm Long-Wave Infrared (LWIR) CO2 laser is reported. Decades of long feasibility studies continue to expand further, through an upgraded multi-TW LWIR laser and optimized 85 MeV electron beam. Benchmarked laser parameters obtained in Orbital Angular Momentum X-ray study utilizing circularly polarized LWIR laser is introduced. Efforts to minimize relative timing jitters associated with low level RF to high power RF across all key locations, with potential feedback controls, is under consideration required by multiple beam interaction experiments such as Bi-harmonic ICS to maximize luminosity efficiently.
