hi!
Here is a short video about the test setup of a cold cathode mercury arc rectifier, just to produce some nice discharges 🙂
Cold Cathode Mercury Vapour Rectifier Tube - Test Setup - YouTube
An AEG J10/1000/1Gl rectifier tube with a cold mercury cathode.
There is a liquid cathode pool on the bottom which consists of a huge amount mercury.
Into this mercury pool, there produdes an ignition electrode (made out of graphite I guess, possibly with a coating).
The Anode consists of a big hollow cylinder, out of graphite as well.
When a sufficiently large ignition pulse arrives, the mercury atmosphere gets ionized and the entire path between cathode and anode begins to conduct with an arc. specs:
- max. blocking voltage, peak value: 15KV
- max. peak current, peak value: 1000A
- max. average current, continuous: 1A
- Application: controlled rectifier for adjustable power, my tubes come from the power supply of a short wave transmitter
- use of a single tube for DC operation, two tubes for AC in inverse-parallel connection

I wonder how much random vibration it can take, before the mercury splashes up and...
Obviously cant be "mounted in any position"...
Fun video, thanks!
