Greetings
I'm working on something which involves high power pulse magnets (It's all on "paper" and in theory, it's academic)
and there is a requirement to switch 1kA current pulses which are quite long (about 1ms - 5 ms).
And there is also a requirement to use electronic tubes due to the nature of the working environment. (present gamma radiation)
Normally a thyratron would have no trouble switching up to 20kA, but the usual pulses for thyratrons are much shorter (most ratings are defined around 3 microseconds).
Certain cold cathode thyratrons can switch up to 200kA for as long as 0.5 miliseconds, which would most certainly do the job, but they suffer from
long recovery time.
And I actually need a device which would recover in a few microseconds (which is typical for regular hot thyratrons in the 10kA ballpark)
Also, there is a requirement for high power tetrodes or triodes, which
can pass about 10 amps in DC mode (no pulses or AC, just DC current),
if such a thing exists.
I don't know that much about tubes, so I'm asking someone which might know more about current world of high power tubes.
So my question is. Does anyone know of a thyratron application where someone succesffully used a stock thyratron for pulses of about 1ms or more at 1kA (is it even possible). The pulses are flat top (square)
And the second question is. Is there such a thing as a triode (or tetrode) which can pass around 10A constant current through anode?
And if this is not the right forum to ask these kinds of things, does anyone have any idea which forum would be best suited for such knowledge?
thank you
