X-ray RF system upgrade at the NSLS

Abstract

A third RF system was commissioned and the existing two systems were modified. Included in the revisions were a new 100 kW, 50 MHz power amplifier, an infra-red heat sensor monitoring the accelerating cavity temperature to compensate for water film coefficient thermal loss, and the isolation of vacuum-RF seals on the accelerating cavity. The results of these changes will be detailed.

A design upgrade of the RF cavity and its power window for high current operation of the NSLS X-ray storage ring

“…The temperature control system is expected to be more responsive than before. The same feedback technique [3], using infra-red detection will be used. The means of detuning will also ble the same as present, which is by insertion of a variable shorting loop in the cavity [3].…”
