Development of a high brightness, high current SRF photo-electron source for ERL applications — Axel Neumann and •Andreas Jankowiak for the bERLinPro Team and Collaborators — Helmholtz-Zentrum Berlin, 12489 Berlin, Germany

Energy recovery linacs (ERL) offer the potential to combine major beam properties of the two main domains of particle accelerators: The low emittance of linear accelerators and the high average beam current of storage rings, while also allowing to compress to short bunches below the ps regime. This makes among other applications ERLs an ideal candidate for future light sources. The beam properties of the ERL are given by the performance of the injection section and hence of the beam source. Helmholtz-Zentrum Berlin is currently designing and building a high average current all superconducting CW driven ERL as a prototype to demonstrate low normalized beam emittance of 1 mm*mrad at 100mA and short pulses of about 2 ps. In this contribution we will discuss the development of this class of a high brightness, high current SRF photo-electron source and present recent commissioning results. Also, alternative approaches at other laboratories will be shortly reviewed.
