Deuterium-Filled Ceramic Thyratron
The data to be read in conjunction with the Hydrogen
Thyratron Preamble.
ABRIDGED DATA
Deuterium-filled tetrode thyratron with ceramic/metal
envelope, featuring low jitter, firing time and drift. Suitable for
switching high power at high pulse repetition rates or for
switching long pulses. A reservoir operating from a separate
heater supply is incorporated.

Cooling by oil or coolant immersion is preferred in view of the
high voltages present. Further information is contained in the
relevant section of the Preamble.
The tube may be cooled by forced-air directed mainly onto the
base, and the metal/ceramic envelope should be maintained
below the maximum rated temperature. An air flow of at least
2.83 m³/min (100 ft³/min), depending on the mechanical
layout, will be necessary to keep the tube operating
temperatures under the limits specified below.
In addition to 300 W of heater power, the tube dissipates from
100 W per ampere average anode current, rising to 300 W/A at
the highest rates of rise and fall of anode current.
The cathode end of the tube must be cooled whenever heater
voltages are applied, since the cathode flange will reach a
temperature of 120 8C above ambient in the absence of cooling.
