Energy Recovery Linac Project at CORNELL

Ivan Bazarov, Cornell University

Energy Recovery Linacs (ERL) pose great potential to deliver 'linac quality' beams but with a high average current comparable to that of storage rings. Cornell University is carefully looking into a possibility of building an ERL based X-ray source that will provide a smaller emittance & shorter pulses than those available from the rings, with a potential of being a better CW X-ray source. There are many technological challenges that must be adequately addressed before such a facility can be realized, in particular, those pertaining to high-average current, high-brightness injectors and superconducting RF technology. I will identify these challenges and summarize R&D activities at Cornell to address them.
