Title Evaluations of Parameters Stability of S-Band RF Gun Cavity Due to Effects of Pulsed RF Heating
Abstract Requirements to high stability of electron beam arrivaltime in modern FEL facilities transform to requirements of high stability of amplitude and phase of electric fied in RF photocathode gun which is used as electron injector. To provide high quality of bunches, gun cavities with high electric and hence magnetic RF fields. Effects, related to pulse RF heating, result in change of the cavity frequency and quality factor during even few μs RF pulse. Cavity deformations due to pulse heating are considered and corresponding cavity detuning are evaluated. Resulting deviations of the phase and amplitude of the RF field in the gun cavity as a function of RF pulse duration are estimated.
