| | In order to increase the protons energy up to 8 GeV
in a driver Linac, the particles must be accelerated
through various stages and three different power levels
(25kW, 100kW and 210kW) are required for the 325
MHz Fermilab Proton Driver couplers. The problem
identified by the project is that no High RF power coupler
for these cavities has ever been designed and produced
using US industrial capabilities. AMAC proposed a novel
resolution by development of innovative modular,
multiple power levels, 325 MHz spoke cavities power
couplers, which to meet three type cavities with one
coupler design. The simulation and concept design are
presented. The results of HFSS, MAFIA, ANSYS, and
Multipacting are also discussed. | |
