The Helmholtz-Zentrum Berlin is constructing the Energy Recovery Linac Prototype BERLinPro, a demonstration facility for the science and technology of ERLs for future light source applications. BERLinPro is designed to acceleration a high current (100 mA, 50 MeV), high brilliance (norm. emittance below 1 mm mrad), short pulse (below 2 ps) cw electron beam. Here the project status will be reported. This includes the completion of the building and the installation of the first accelerator components, as well as the assembly of the srf gun and GunLab beam diagnostics, which are now under commissioning.

Helmholtz-Zentrum Berlin (HZB) is currently constructing an high average current superconducting (SC) ERL as a prototype to demonstrate low normalized beam emittance of 1 mm·mrad at 100mA and short pulses of about 2 ps. To reach the required beam properties, an SRF based photo-injector system was developed and recently underwent RF commissioning. The medium power prototype- a first stage towards the final high power 100 mA design- presented here features a 1.4 x λ/2 cell SRF cavity with a normal-conducting, high quantum efficiency Cs2KSb cathode, implementing a modified HZDR-style cathode insert. This injector potentially allows for 6 mA beam current and up to 3.5 MeV kinetic energy, limited by the modified twin TTF-III fundamental power couplers. In this contribution an overview of the design approach, cavity production and module assembly up to the first RF commissioning results of the photo-injector module will be presented.
