Theory of the special Smith-Purcell radiation from a rectangular grating
TL;DR: The recently uncovered special Smith-Purcell radiation (S-SPR) from the rectangular grating has significantly higher intensity than the ordinary SPR and its monochromaticity and directivity are also much better as discussed by the authors.
Generation of quasiequally spaced ultrashort microbunches in a photocathode rf gun
TL;DR: In this article, the authors proposed a scheme to restrain the space charge forces by expanding the transverse size of the laser pulses to reduce the charge density and adopting a multicell gun to increase the beam energy.

Electron bunch length measurement with a wakefield radiation decelerator
Weiwei Li,Zhigang He,Qika Jia +2 more
TL;DR: In this paper, the electron bunch length was measured with a dielectric wakefield radiation (DWR) decelerator, which is composed of two Dielectric-lined waveguides (DLWs) and an electron spectrometer.

Broad-tunable terahertz source with over-mode waveguide driven by train of electron bunches.
TL;DR: Compared with other sources, the proposed source is compact and easily achievable, and the tunable radiation with frequency extending from 0.1 THz to 1.2 THz can be obtained from one single structure model.

Tunable THz radiation source from dielectric loaded waveguide excited by nonrelativistic electron bunch trains
TL;DR: In this article, a train of laser pulses with THz repetition rate is used to drive a photocathode direct current (DC) gun, leading to the emission of electron bunches, which is subsequently accelerated by the gun field and applied to selectively excite one of the modes in the dielectric loaded waveguide (DLW) structure.
