Description
The COBRA source (Compton Backscattering at a Recirculating Accelerator) utilizes a 100 W Yb:YAG laser that is synchronized with the electron beam of the superconducting Darmstadt linear accelerator S-DALINAC * for head-on collisions. The backscattered photons in the X-ray energy range can be collimated into a quasi-monochromatic beam for electron beam diagnostics and as a technology demonstrator. The first collision of the electron and laser beam is planned in an upcoming beamtime with multi-turn recirculation. During operation, COBRA utilizes stabilization systems for both beams. Later, COBRA is foreseen to be operated during energy-recovery mode **, serving as a demonstrator for future Compton scattering light sources. This contribution provides an overview of the COBRA source, highlighting recent upgrades to the detector setup and developments of the laser beamline.
