Solid state systems

Talk

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...

Klystrons

Talk

The Continuous Electron Beam Accelerator Facility (CEBAF) at Jefferson Lab was upgraded to 12 GeV in 2014, necessitating the use of high-power klystrons. The C75 and C100 cryomodules, which enable the 12 GeV operation, are capable of achieving higher gradients and are powered by 8 kW and 13 kW klystrons, respectively. Over the past decade of operating at 12 GeV, we have observed a decline in...

31. RF Conditioning Operations and System Updates of the High-Power RF Test Facility in the Spallation Neutron Source

Power transmission and distribution

Talk

The conditioning of RF components and their proper storage are crucial for stable and reliable Linear Accelerator (LINAC) operation. The Radio-Frequency Test Facility (RFTF) was built to test the RF subsystems and to condition the RF windows and couplers of the LINACs at the Spallation Neutron Source (SNS). It consists of two waveguide systems operating at 402.5 MHz and 805 MHz, powered by...
