Abstract
In partnership with the US Navy, high-technology corporations, and research universities, Jefferson Lab is building a superconducting radio-frequency (SRF) accelerator-driven free-electron laser (FEL) and is outfitting an FEL user facility. This first fourth-generation light source – a 1 kW, 3 μm infrared (IR) laser – is the first step in a program to develop high-average-power SRF-based IR and ultraviolet (UV) FELs for multiple manufacturing applications as well as for defense-related applied research and basic scientific research. This initial FEL will be driven by a 42 MeV, 5 mA recirculating SRF linac similar to the much larger SRF linac in Jefferson Lab's 4 GeV, 200 μA Continuous Electron Beam Accelerator Facility (CEBAF). The FEL is expected to demonstrate 75% energy recovery. Its linac will be cooled by the existing CEBAF cryogenic system. At Jefferson Lab, an infrastructure of facilities and people already supports the advance of SRF and closely related technologies in the furtherance of the lab's primary mission of nuclear and particle physics. This paper summarizes the opportunity represented by SRF-driven FELs and reports on the program now underway to develop them.
