(1) 6-32 tapped hole in non-tubulated end.
(2) Identical tubulation on both ends.
(3) The voltage level at which the spark discharge occurs when a unipolarity pulse train is applied to the gap. Typically, the pulse repetition rate is 400 pps (pulses/second) with a rise
time of 0.3 µs and a pulse width of 0.5 µs. The “initial” range specifies at what increasing voltage the gap begins to fire and the “rep” range specifies at what decreasing voltage the
gap ceases to fire repetitively.
