Spark Gap Tubes

Anyone have experience with spark gap tubes
(sometimes called TR tubes) from radar modulators?
I checked the archives and found a brief mention,
but it does not look like anyone experimented with
them. They were referred to as vacuum gaps, but
this is incorrect, since they are gas filled and often
pressurized. They seem to have impressive
specifications, but the construction does not look
like it could support the power levels quoted. My
guess is the peak power is high, but the average
power must be rather modest. I have a 1B22 which
is rated at 67AMPS for 0.75ms at 1000 PPS, or
2.25ms pulses at 330 PPS. Conduction starts at
2.7KV, about in MOT range. Big problem is, no
adjustments to the gap are possible.
