High Repetitive Photocathode RF Gun

  1. Feb 23, 2014 #1
    Hi fellows,

    I've been looking for "High Repetitive Photocathode RF Guns" for more than a couple of days. It seems, first I need to understand the RF Guns.

    I deciced to search such a document that gives the history of RF Guns and explains their historical background with working principle. So I can understand better the deal that I have.

    So far I've got just the scientific articles that gives really really short infos about what I'm looking for.

    Does any of you, please, help me on this topic?

    Will be waiting for your help.

    Try looking for the history of the free electron laser.

    Or try looking for review articles on this topic. It is all too new for there to be any history articles!

    PS: What are the specifications for the laser you are interested in? I build laser-driven photo-electron guns.

    Problem here is that you have not revealed what you already know. You need to know a bit about the basic principles of particle accelerators before moving on to photoinjectors. Have you studied out of, say, Wangler's classic text?

    Dear UltrafastPED and dear Mentor ZapperZ,

    Thank you so much for your interests and posts.

    You are right, of course I should have mentioned what I studied before and what I know to get a proper answer.

    I know a bir about FEL's and their principles, physics, basics whatever you say. Also I know about thermionic e- sources a little, how they operate, basics etc.

    The reason of my question was related about my willing to understand and learn about RF guns and especially photocathode rf guns.

    A path that indicates from the beginning and simplified will be great.

    Thank you so much for your kind answers again.

    Best,

    So have you studied the basics of accelerator physics, such as the various waveguides and EM modes that can exist (standing and traveling) in those various geometries? In other words, stuff out of Wangler's text?

    I studied about the basics of FEL's. I mean that, I know something about thermionic electron guns and TESLA cavities.

    I did not completely read Wangler's book if you say that but I've read some parts from it.

    Anyway, thank you for your advise. I'll start to read Wangler's book completely.

    Best,

    The reason I asked that is that an rf photoinjector has the same physics as any accelerating structure. The major difference being that this is where the photoelectrons are also created out of the photocathodes at one end of the structure. So one has to start with the understanding of accelerating structures.
