The use of infrared lasers to power optical-scale lithographically fabricated particle
accelerators is a developing area of research that has garnered increasing interest in recent …

Traditional tube-based x-ray sources are widely employed in medical imaging, security
screening, and industrial inspection. The cone-beam produced by these tubes is simple to …

We propose a new type of terahertz (THz) radiation source based on the electron beam-
wave interaction. A high-order harmonic-generation process was introduced to a traveling …

A high-harmonic traveling-wave tube (HHTWT) is designed, developed, and tested in this
paper. This device is configured as a multiplier-amplifier with Q-band input signals and its …

In this article, deep reinforcement learning (DRL) is utilized to explore high-performance
folded-waveguide (FWG) slow-wave structures (SWSs) for broadband application in …

A new type of folded frame slow-wave structure (SWS) is introduced and used in the design
of a low-voltage, high-efficiency, and widebandwidth millimeter-wave traveling-wave tube …

Laser powered accelerators have been under intensive study for the past decade due to
their promise of high gradients and leveraging of rapid technological progress in photonics …

This book contains the contributions to the Workshop on the Physics and Applications of
High Brightness Electron Beams, held in July 2002 in Sardinia, Italy. This workshop had a …

The performance of a field-enhanced emitter (FEE) array in an enclosed and ex-situ
operated device has long been known to deviate from the ideal characteristics observed in …

We report progress on the design and construction of a nine-cell cavity operating in a TM
110-like dipole mode for use as a temporal diagnostic of the 14 MeV, 300 pC electron …
