Klystron Department

Lecture Series

TIMING 11a.m.-12 p.m., Panofsky Auditorium.
MEDIUM: Streaming Video  (Accessible through the SLAC Klystron Department web page)
  1. Class notes, also posted on web.

  2. Chapter 3, “Klystrons” in forthcoming MURI “Vacuum Electronics Devices” book. (MURI is the Air Force “Multidisciplinary University Research Initiative”)

  3. “Power Klystrons Today” Smith and Phillips.

PREREQUISITES: Algebra, trigonometry, calculus and basic physics.  
LECTURES: Following is a tentative listing of the class presentations.  Some rescheduling  will be necessary from time to time due to unexpected travel or auditorium conflicts. 

The fully processed streaming video will be available on the Web a week after the auditorium presentation.

We suggest that you download the "Lecture notes" prior to viewing the video, so that both the slides and the "speaker's notes" are available to follow as you listen to the speaker. The lecture notes may be slow to download, because some of them are large files.


1.  01/14/04 Discussion of today’s major applications.  Radar, accelerators, UHF television, satellite communications, millimeter wave transmitters. Examples (pictures) of klystron types. Historical perspective.  (G. Caryotakis) Lecture Notes MURI Book 1.     MURI Book Appendix 1.
2.  01/21/04 Velocity modulation, kinematic theory. (G. Caryotakis) Lecture Notes ; MURI Book 2
