Development of High Frequency Resonators for Proton Acceleration in the Energy Range from 2.3 Till 5 MeV

High frequency optimization of multigap IH-/CH-resonators requires solving the range of problems, particularly receiving high values of effective shunt impedance and realization of the uniform accelerating field distribution on its axes. H-mode resonators design contains flat vanes (pylons)to reach both of these goals. This article presents the results of electrodynamic modeling of CH- and IH-resonators in case of zero gap between the vanes and resonator end wall. The values of the optimized shunt impedances, Q-factor and field flatness for IH- and CH-designs are shown.
