Notes:
[1] It is the maximum peak voltage under the condition of resonant charging.
[2] Peak inverse anode voltage (include peak) must not exceed 10KV within 25 μs after impulse
current discharge finished, otherwise it will damage the grid and cause spark inside the tube and
shorten the working life.
[3] This rate of rise refers to that part of the leading edge of the pulse between 26% and 70% of the
pulse amplitude.
[4] Measured with respect to cathode. Pre-pulsing of grid 1 is recommended for high rate of rise of
current applications.
[5] The higher grid 1 is pulsed, the larger must the grid 2 negative bias be, to prevent the tube firing on
the grid 1 pulse.
[6] The tube must be fitted using its corresponding 5-pin board.
[7] If the tube is cooled by forced-air, an air flow of at least 2.83 m3
/min is required.
[8] The time interval between the instant at which the rising unloaded grid 2 pulse reaches 26% of its
pulse amplitude and the instant when anode conduction takes place.
[9] Anode firing delay time drift, the drift in delay time over a period from 10 seconds to 10 minutes
after reaching full voltage, its anode firing delays time of change.
