Modeling multipacting to steady state saturation is of interest in determining the performance of micro-pulse electron gun. In this paper, a novel method is proposed to calculate the multipacting resonance parameters for the gun. This method works we

The maximum radiation efficiency can be obtained when the feed array excitation of a reflector antenna is synthesized by the conjugate field matching (CFM) method. However, the CFM method can only get the strongly tapered feeding power distribution.

When ultrasonic guided wave are used for icing detection, the multimodal and dispersion characteristics of guided wave make the guided wave signal very complicated, and it is difficult to identify time domain signal directly. Wavelet packet decomposi

A corrugated structure is built and tested on many FEL facilities, providing a ‘dechirper’ mechanism for eliminating energy spread upstream of the undulator section of X-ray FELs. The wakefield effects are here studied for the beam dechirper at t
