Accelerators and Lasers In Combined Experiments (ALICE), or Energy Recovery Linac Prototype (ERLP) was a 35MeV energy recovery linac test facility at Daresbury Laboratory in Cheshire, England. The project was originally conceived as a test bed for the 4th Generation Light Source (4GLS), and consisted of:A 350keV photoinjector laser. An 8.35MeV superconducting RF booster linac. A 35MeV superconducting RF main linac in which energy is recovered from used electron bunches and given to new bunches. An infrared free electron laser (FEL), using a permanent magnet undulator on permanent loan from Thomas Jefferson National Accelerator Facility (TJNAF). An ERL transport system that transported electron bunches through the FEL and back to the linac with the correct RF phase to decelerate them and thereby to recover energy from them.
