Performance of RF System for Compact-ERL Main Linac at KEK
The construction of compact ERL in the first stage has been completed in the end of 2013. The rf commissioning in main-linac has been started. The main-linac consists of two nine-cell cavities. The loaded Q is high, ~10⁷. As the rf power sources, a solid state power amplifier and an inductive output tube (IOT) has been used for two cavities, respectively. The RF field and tuner have been successfully controlled by using micro-TCA digital feedback board. This paper reports about the RF commissioning and the performance.doi:10.18429/jacow-ipac2014-wepme073 fatcat:52vjq4vsvfc7vhcycqgxfxm6pi
