Megatron's 2nd cousin twice removed is named Klystron.

Nah, seriously though a klystron is an RF amplifing device used in radars (see picture below).
My first real job in the navy was a radar tech and my radar system used a klystron. It was pulsed with 90,000V to amplify a tiny 3GHz RF signal into a 1MW output.
At that level of power there needs to be a series of focus coils (basically large electro magnets; not pictured) encircling the body of the klystron to keep the beam of RF 'focused' as it travels up and out of the device. if the beam is off slightly it will burn right thru the top of the klystron, instead of correctly entering the waveguide, and literally slag everything in its path (yes, this did happen).

I thought ending with "tron" and being an actual real world device, as well as one from my past, all fit together as a suitable username.
