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 resulting pulses can lead to several potential applications, from quantum X-ray optics to visualizing electron motion inside molecules. "We have observed strong lasing phenomena in inner-shell ...

Operating principle Simulated longitudinal electron speeds, from blue (stationary) to orange (fast), overlaid on a simplified schematic of a TH2167HE-style klystron. An electron gun (left) emits ...

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 ...
