Thyratrons- particularly the hydrogen type- still have uses although they aren't as widely used as they used to be. Large particle accelerators are still dependent on them to produce the pulse power for driving the klystrons. In transmitters and particle accelerators using inductive output tubes they are used in the crowbar circuit used to protect the IOT from damage due to internal arcing.
It's pronounced thigh ra tron, not theryatron. I wondered why I had never heard of these the first few times you mentioned it! Thyratrons were also used in some vintage TV timebase circuits.
@@GearAcquisitionSyndrome Well, I do have a degree in engineering and electrical sciences, and always tinkered with old post war TVs as a boy, which is where I first came across thyratrons. My uncle told me how to say it, he was also keen on electronics.
I've also got a degree in electrical engineering and English is my second language. I'll probably use the pronounciation you suggested, it's less of a hassle
@@GearAcquisitionSyndrome I just remembered that I know two people who used to work at the STC factory in Paignton. They both mentioned thyratrons and used the pronunciation I advised. One said that the test room had a strong smell of ozone from the high voltage corona discharge.
The power through some of these tubes is astonishing.
Yes, it truly is!
Thank you for sharing this.

The semiconductor equivalent of that tube is a thyristor.
i have a huge one from an old small cinema audio amplifier. but the tube is big
24:05 isn’t that an x-ray tube?

I'm under the impression nobody knows what they're pronounced. I'm joking, you might be right!

Years ago I was an enthusiast for old TV's. Were there any post-war TV's that used thyratrons for the timebase?
19:32 thats a mercury thyratron, i think.
those are droplets of mercury
The GU-81M is a pentode not a tetrode
Thy ra tron. three syllables, not four.
