High power test of new alumina ceramic for S-band rf vacuum window was performed. In order to estimate performance of only ceramics, we used Helicoflex seal type rf window instead of vacuum brazing seal between metal and ceramics. This window was not damaged at peak power of 58MW, pulse width of 4μsec and repetition rate of 10pps from direct klystron output power. By using SLED (Stanford Linear accelerator Energy Doubler), it had also no damage at peak power of 330MW, pulse width of 1μsec and repetition rate of 10pps.
