The sheet beam electron gun is one of the most important parts of a sheet beam traveling wave tube (SB-TWT). In this paper, a 220 GHz sheet beam electron gun is designed and optimized by using CST.

This article introduces an innovative design for a thermionic grid-controlled RF electron gun that utilizes a spoof localized surface plasmons (SLSPs) structure as the grid. The strong resonance and ...

The experiments were performed at the Linac Coherent Light Source at SLAC National Accelerator Laboratory and the SACLA X-ray laser at the Japan Synchrotron Radiation Research Institute. /Public ...

Perveance The main characteristic of a klystron is an obscure magnitude inherited from electron-gun design called perveance.

Figure 1 A greatly simplified drawing of a helix-type TWT shows 1) electron gun; 2) RF input, 3) magnets, 4) attenuator, 5) helix coil, 6) RF output, 7) vacuum tube enclosure, and 8) collector. Source ...
