Abstract

A new 50.58 MHz RF system has been installed in the Aladdin synchrotron light source at the University of Wisconsin-Madison. A more compact aluminum RF cavity was constructed to make the original RF straight section available for a future insertion device. The original grounded cathode 4CW100000E power amplifier was also modified to improve its stability and control system. The new system delivers enough power to run the cavity at maximum gradient while supporting large beam currents. New low level RF electronics were constructed, including low level RF feedback. Feedback allows the use of a smaller RF bucket at injection to improve beam capture and eliminates operational difficulties with the Robinson instability. Operational results with the new system are presented
