Higher electronic efficiency RF power generation

EnEfficient - an activity within the European effort

Higher electronic efficiency RF power generation

Task: 3.3

This task is led by CERN.
Contact: Erk JENSEN at CERN
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
