BERLinPro- A PROTOTYPE ERL FOR FUTURE SYNCHROTRON LIGHT SOURCES

The HZB (previously BESSY) was the first institution in Germany to build and operate a dedicated synchrotron light source (BESSY I). About 10 years ago BESSY-II, a third generation synchrotron light source, was commis-sioned. Presently, HZB is developing a design for a future multi-user light source as a successor to BESSY II and to enable ”next-generation ” experiments. Such a facility will be based on the energy-recovery-linac (ERL) principle. Al-though ERL facilities exist for the IR and THz range [1],[2] their moderate parameters (current, emittance, energy) are insufficient for x-ray sources. HZB is therefore propos-ing to build a prototype ERL facility (BERLinPro) that will demonstrate high current and low emittance operation at 100 MeV. BERLinPro is intented to bring ERL technol-ogy to maturity so that it can be employed for x-ray light sources. This paper presents an overview of the project and the key components of the facility
