Description
CERN has been operating two 1.6 MW peak power SSPA systems at 200 MHz for the past 4 years. This novel amplifier system combines 16 x 80 x 2kW peak power amplifiers in cavity combiners, then uses a network of high power hybrid combiners to reach the desired power levels. The SPS operates both in high power CW (750kW in the seconds range) and high power pulsed mode (1.6 MW in the microseconds range) which is highly stressing to the amplifiers. Operational experience and a review of reliability difficulties alongside troubleshooting methods will be presented.
