Based on previous experimental investigations on pseudospark (PS) discharges, a small-scaled PS electron beam source was conceived to drive a 200GHz microklystron. Recent PS e-beam experiments producing a beam of 1mm in diameter and klystron interaction simulations will be presented. The microklystron will be fabricated using micro-electro-mechanical systems (MEMS) construction techniques.
A multicavity microklystron operating in the terahertz region has been designed and simulated. This microklystron will be driven by an electron beam sourced by a down-scaled pseudospark discharge.
Summary form only given: Demands in plasma diagnostics, radiotherapy, medical research and advanced communications have in recent years resulted in the development of new radiation sources in the terahertz region (0.1 to 10 THz). A klystron is one attractive choice for generation of THz radiation due to its operation mechanism, efficiency and robustness and because its structure is amenable to being...
Summary form only given. Terahertz radiation, which ranges from 0.1 THz to 10 THz, has received substantial interests in recent years. The conventional vacuum electronics technology has the potential to supply high enough powers to underpin many exciting and emerging THz applications. Klystrons have been designed to generate THz radiation. This vacuum device requires a very small sized RF circuit...

Realization of the concept for a high-power ribbon- beam klystron (RBK) requires a novel large-aspect ratio elliptic electron beam instead of a conventional circular electron beam. In this paper, a cold-fluid equilibrium theory of a nearly non-twisting intense elliptic charged- particle beam is presented. The equilibrium theory is applied in designs of elliptic electron beams for high- power RBKs...
