My coworker brought in a big electron tube/valve. Anybody wanna guess what it is?
(@tubetime probably already knows)

1. A large clear vacuum tube with some metal fins inside it. It's about a foot (30cm) tall with a thick metal base

2. the base of the tube, which appears to be made of cork. it has 5 thick pins arranged in a circle

  @foone @tubetime a little searching and I'm coming up with the words "deuterium thyratron", which I'm going to need you to explain.

  @vathpela @tubetime correct! I'm not really sure why it needs to be full of deuterium, but it's a thyratron, acting as a switch/rectifier.

  @vathpela got it! It's a thyratron filled with deuterium gas. (or it was. it's probably leaked by now)
  that's used as a switch/rectifier.

  1. Thyratron
    
    A thyratron is a type of gas-filled tube used as a high-power electrical switch and controlled rectifier. Thyratrons can handle much greater currents than similar hard-vacuum tubes. Electron multiplication occurs when the gas becomes ionized, producing a phenomenon known as Townsend discharge. Gases used include mercury vapor, xenon, neon, and (in special high-voltage applications or applications requiring very short switching times) hydrogen. Unlike a vacuum tube (valve), a thyratron cannot be used to amplify signals linearly. In the 1920s, thyratrons were derived from early vacuum tubes such as the UV-200, which contained a small amount of argon gas to increase its sensitivity as a radio signal detector, and the German LRS relay tube, which also contained argon gas. Gas rectifiers, which predated vacuum tubes, such as the argon-filled General Electric "Tungar bulb" and the Cooper-Hewitt mercury-pool rectifier, also provided an influence. Irving Langmuir and G. S. Meikle of GE are usually cited as the first investigators to study controlled rectification in gas tubes, about 1914. The first commercial thyratrons appeared circa 1928. The term "thyratron" is...

  @foone My first thought was "rather inadvisable buttplug" and then I decided I probably ought not to have any more thoughts today.

  @baljemmett I'm pretty sure my sex ed class had a whole day spent on "don't put electron tubes in your butt"

  @foone @baljemmett I can tell you went to a technical school... :)

  @baljemmett I would argue that making electron tubes with flared bases would be even more dangerous than not.
  (Because if it doesn't have a flared base, hopefully that'll discourage slightly more people to not put it in their butt. )

  @foone Especially ones without a flared base!

  @robinsyl I hope you cover it with some lead shielding though, because this thing emits x-rays!
