    An energy-recovery linac (ERL) R&D program for a high-power free-electron laser (FEL) is in progress at Japan Atomic Energy Agency (JAEA; formerly JAERI and JNC). The first energy-recovery operation and FEL lasing was demonstrated in 2002 by remodeling the superconducting linac of the JAERI-FEL driver. In the first demonstration, the accelerated beam current was same as the original linac. One of the advantages of an ERL is that the accelerating beam current can be increased by only changing micro-pulse repetition rate without increasing the RF power of the main linac. The advantage of an ERL has been demonstrated by the current doubling.
