RE: [TCML] Klystron use?
I am searching for these books right now.
HYPER AND ULTRA HIGH FREQUENCY ENGINEERING - ok found it
ULTRA HIGH FREQUENCY TECHNIQUES - ok bid on it
!!!!!!!!!!!!!! THANKS !!!!!!!!!!!!!!

Might want to check out these books.HYPER AND ULTRA HIGH FREQUENCY
ENGINEERING BY SARBACHER AND EDSON and ULTRA HIGH FREQUENCY TECHNIQUES BY
BRAINERD AND WOODRUFF. I picked them up on ebay awhile ago. Both are from
WWII era but as you most likely know this was perhaps the period of most
interest in these gems. Just a suggestion. Wyatt Sent from my Verizon

Thanks very much, but this link seems to be one of those pay for the article
sites. Humm, I really need something that I can read up on to "stimulate"
thoughts of a tesla application. It will be hard to glean any useful
information by reading 10% of an article.

This might be a start : http://www.tpub.com/content/fc/12404/index.htm
scroll down to the basic radar systems and you will see a heading called
Klystrons
http://www.tpub.com/content/fc/12404/css/12404_32.htm
They give some basic understanding and state that Klystrons can be
understood better by looking at Triode resonant amplifiers with
restricted bandwidth and increased gain.. - they have a few schematics
to view online there.....
There is quite a bit involved - this site might put you off firing one
up (just the cooling schemes are quite involved alone) - but just like
putting a ship inside a bottle - its worth the effort some would say..
Good Luck.
