Abstract: In this work we developed a new rf deflector based on the H resonator, which differs from previous ones in its design, the type of rf fundamental mode and the possibility of providing the pi-mode standing wave for the beam in the deflection system. Because of the last aspect, the transverse shunt impedance of this deflector is much higher in comparison with its analogues. This idea was originally intended for application in the funneling system of the European Spallation Source, but we later found many additional applications, in particular, as the bunch separator after the electron and proton linear accelerators. We studied the beam dynamics and the electrodynamics and optimized the device parameters in the assumed range of frequency of 150-700 MHz for the proton beam and 1000-1500 MHz for the electron beam. To make the final choice we analyzed rf deflectors of different designs. We manufactured the experimental sample tested at the low rf power level.
