Lecture 1 Linear Beam Devices and Slow Wave Devices

Prof. John Booske

Univ. of Wisconsin, USA

This lecture will compare and contrast vacuum electronic and solid state electronic high frequency devices. It will then present an overview of linear beam tubes such as klystrons, traveling wave tubes and their derivatives. The beam wave interaction mechanism and the physics of electron bunching and energy extraction will be discussed. Finally, the state-of-the-art in such devices and their recent advances will be discussed.

Lecture 2 Crossed-Field Devices

Prof. Edl Schamiloglu

Univ. of New Mexico, Mexico

The invention of the cavity magnetron in 1940 and the subsequent development of radar and industrial applications are considered a "major innovation" according to the definition often used by technology historians. Today, industrial cavity magnetrons abound and routinely operate reliably with beam-to-microwave conversion efficiencies exceeding 80%. This lecture will review crossed-field devices arcing from the cavity magnetron in 1940 to the relativistic magnetron which in recent simulations have suggested operating with 92% efficiency.

Lecture 3 Fast-Wave Microwave Devices

Prof. Manfred Thumm

Karlsruhe Institute of Technology , Germany

This lecture will cover an introduction to fast-wave microwave devices such as gyro-oscillators, gyro-amplifiers, and free electron masers. The beam wave interaction mechanism, physics of electron bunching and energy extraction will be discussed. The development of continuous wave gyrotrons with megawatt level power for use in heating, non-inductive current drive and diagnostics of fusion plasmas will be presented. The lecture will also cover the development of terahertz gyrotrons for use in novel applications such as in spectroscopy and the use of gyro-amplifiers in millimeter-wave radar.

Lecture 4 Free-Electron Lasers; from Terahertz to X-rays

Prof. Kwang-Je Kim

Univ. of Chicago & Argonne National Lab, USA
