We demonstrate the electromagnetic performance of waveguides for femtosecond electron
beam bunch manipulation and compression with strong-field terahertz (THz) pulses. The …

Gyrotrons are used as high-power sources of coherent radiation operating in pulsed and
CW regimes in many scientific and technological fields. In this paper, we discuss two of their …

We present the design, fabrication, and cold testing of a THz-driven field emission electron
gun. The gun is designed as a two-cell standing-wave structure with a copper tip inserted …

The development of ultracompact particle accelerators and accelerator-based high-power
THz generators are some of the top priorities for research and development programs …

We present preliminary testing results for single-cell accelerating structures intended for
high-gradient testing at 110 GHz. The purpose of this work is to study the basic physics of …

We present the design of a high-gradient electron gun. The goal of this gun is to generate
relativistic electrons using GV/m accelerating fields. The initial design is a standingwave …

Experiments with high gradient traveling-wave mm-wave metallic accelerating structures
were performed to research the physics of vacuum rf breakdowns. The accelerating …

We are exploring the physics of vacuum rf breakdowns in high gradient metallic accelerating
structures at sub-THz frequencies. We present the experimental results of rf tests performed …

In this thesis, the use of a rectangular dielectric-lined waveguide for energy modulation of
electron bunches is presented. The choice of waveguide allows for guided THz pulse …

This paper presents an application of the powerful field modal expansion theory, to derive a
mm-wave" open" cross-section gaussian horn antenna starting from a standard closed cross …
