Abstract :
The single-cell 352 MHz cavity for the APS 7-GeV positron storage ring has been tested up to one megavolt gap voltage at 100 kW. Thermal measurements were recorded to ensure adequate cooling. Higher order modes were damped using both voltage and current coupled dampers. The dampers have less that the fundamental mode. Stagger tuning of the higher modes has been done by slightly varying the length of each cavity to shift them apart in order to minimize their effect of multi-bunch instabilities
