Work on the double-spoke superconducting cavity started in early 2021. By January 2023, two prototype 324 MHz cavities had been successfully built and tested, achieving vertical test gradients of ...

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 ...

Terahertz optics articles from across Nature Portfolio Terahertz optics is a branch of optics and photonics that studies electromagnetic radiation with a wavelength between 0.1 and 1 millimetre ...

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.

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 ...

Ultrafast pump–probe spectroscopy (13) and Raman spectroscopy (10) are experimental techniques that offer valuable, albeit indirect, insights into nonequilibrium anharmonic phonon scattering and ...
