THE UCSB 2 MV MM-FEL - CHARGING SYSTEM

To achieve CW operation, a high capacity charging system will be utilized. A total of eight chains with new high current induction electrodes have been installed. This will make available 2.0 mA of which 400 µA is used for potential grading and the remaining 1.6 mA current is available to accommodate beam loss, thus requiring 99.92 % recirculation for CW operation.
