There is considerable interest in using superconducting electron linacs with energy recovery as synchrotron radiation sources. Such energy recovery linacs (ERLs) would open new regimes of X‐ray science because they are capable of producing ultra‐brilliant X‐ray beams [>5 × 10 22 photons s −1 (0.1% bandwidth) −1 mm −2 mrad −2 at 10 keV], maintaining a very small source size (∼3 µm r.m.s.) suitable for micro X‐ray beams, and making very intense fast (∼100 fs) X‐ray pulses. Each of these characteristics would permit the execution of experiments that are not feasible with existing synchrotron sources. Many technical issues must be satisfactorily resolved before the potential of a full‐scale ERL can be realised, including the generation of high average current (10 to 100 mA), high‐brightness electron beams (0.015 to 0.15 nm rad emittances, respectively); acceleration of these beams to energies of 5–7 GeV without unacceptable emittance degradation; stable and efficient operation of superconducting linear accelerators at very high gradients etc . Cornell University, in collaboration with Jefferson Laboratory, has proposed to resolve these issues by the construction of a 100 MeV, 100 mA prototype ERL. The intention is to then utilize the information that is learned from the prototype to propose the construction of a full‐scale ERL light source.
