High-flux and narrow-bandwidth LCS photon beam is realized in an energy recovery linac (ERL). An electron beam of high-average current and small-emittance collides with accumulating laser pulses in an enhancement cavity for generating high-flux LCS photon beam. We have developed the high-finesse bowtie ring cavity for the LCS experiment at the Compact ERL (cERL) in KEK. In this presentation, we will report the detail of the optical cavity., 2016 North American Particle Accelerator Conference (NAPAC16)}, title = {DEVELOPMENT OF AN OPTICAL CAVITY FOR LCS SOURCES AT THE COMPACT ERL}, year = {2016} }
