Abstract
A double rf system is installed in order to suppress a longitudinal co upled bunch instability by Landau damping for the free electron laser experiment in the ETL storage ring TERAS. Coherent instabilities of th e stored electron beam have been reduced by exploiting a Landau cavity with the second harmonic of the accelerating frequency 171.62 MHz. Th e significant improvement in the electron beam quality contributes to the success in the first lasing of visible FEL at TERAS.
