摘要

<正> In the simmer of 2002, long-term operation of SSC RF cavities at high RF voJtage was carried out. The designing voltage for SSC RF cavities is from 100 kV at 6.5MHz to 250 kV at 14 MHz, respectively. According to the designing values, two operation frequencies were selected for increasing SSC cavities' RF voltages. The RF voltage was raised to 90 kV at lower frequency point 7.374 95 MHz and 200 kV at higher frequency point 13.541 9 MHz.During the operation, many problems were encountered as increasing SSC RF cavities' voltage. For SSC northern RF cavity, some unexpected modulations occurred when RF voltage surpassed 130 kV at 13.541 9
