Do your screen name and avatar have any special meaning or did you just pick a random name and a cool pic? Some are pretty self explanitory, but others can be much more inspired.
Let's hear it...
Uh, screen name: Klystron : means a drift tube that bunches electrons as they travel, not unlike a gun barrel.
Used to be a RADAR tech. While joining the Physics Forum (PF), "magnetron" was already taken, so I chose a different amplitron tube: a klystron.
Haven't been able to insert avatar yet but it'll probably be a USAF TAC (tactical air command) patch pic. Thanks.
