Abstract :
The free-electron laser (FEL) linac has been modified to the energy recovery linac (ERL) at the Japan Atomic Energy Research Institute (JAERI) to achieve the higher power FEL of the next stage of 5-10 kW. Energy recovery has been successfully demonstrated up to 5 mA of average current. Upgrade of the injector is in preparation to accelerate the higher average current of 40 mA. We review transverse instabilities and present experimental data on transverse beam breakup (BBU) obtained at the JAERI ERL-FEL. We compare measurement with simulation
