example: study of multi-beam IOT by company CPIRF Power: 1 MWfrequency range: 650-750 MHz
example: study of multi-beam IOT by company CPI
RF Power: 1 MW
frequency range: 650-750 MHz
for accelerators with high beam power the conversion efficiency from grid to beam is of utmost importance, e.g. ESS, ILC, CLIC, LHeC
  • study efficiency of conventional power sources: klystron, sheet- and multi-beam; also power distribution schemes
  • new devices and concepts, e.g.:
    • multi-beam IOT’s with solid state driver
    • magnetrons with better stability
    • RF aspects of energy recovery linac for LHeC with 400MW beam power
  • direct recovery of electrical energy from spent RF

Example of Effcient RF Generation

  • IOT’s can reach higher efficiency (theoretical 78%) than klystrons and have advantages with regulation behavior
  • however, today the max. power is insufficient multi-beam IOT’s could provide sufficient power while keeping the advantages
