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.

Particles that are far from the core of a bunch are often lost in an uncontrolled way within an accelerator, and in high-current machines beam loss can quickly damage accelerator components or cause significant residual activation. We give a brief overview of the common sources of unwanted beam, including halo generated by nonlinear dynamics, dark current from field emission in the cavities, out-of-time scattered laser light on the cathode, and incompletely blocked laser pulses. The results of tracking simulations to model these effects in BERLinPro are discussed.
