The main thyratron inside a high voltage cabinet. The thyratron is a large vacuum tube with a high voltage input cap at the top of the tube via a small diameter tube. A thyratron is a very fast switch that can dump massive amounts of current, which goes into the Pulse Forming Network of the linear accelerator. Use of a grounding stick and cabinet interlocks keeps us safe while changing the very expensive and fragile thyratron.

I replaced a main thyratron for a linear accelerator this morning. This new thyratron glows slightly blue. A thyratron is basically a very fast high power switch. It costs about $3000 a thyratron, and of course, it's super fragile. They need to be replaced fairly regularly. It should be noted that the bad thyratron that was taken out was very hot, and precautions should be taken for that. Gloves are worn to stop oils from fingers from causing hot spots on the glass cause it to crack.
