Thyratron Preamble.

ABRIDGED DATA

Hollow anode, deuterium filled, five-gap thyratron with ceramic

envelope, featuring high peak current, high rate of rise of

current, low jitter and voltage/current reversal.

The patented hollow anode structure enables the tube to cope

with inverse voltage and current without consequent reduction

in its high voltage hold-off capability due to electrode damage.

A reservoir normally operated from a separate heater supply is

incorporated. The reservoir heater voltage can be adjusted to a

value consistent with anode voltage hold-off in order to achieve

the fastest rate of rise of current possible from the tube in the

circuit.

Cooling

For all applications, cooling by oil or coolant immersion is

desirable. Further information is contained in the relevant

section of the Preamble.

At and below 55 kV the CX1594 may be cooled by forced-air

directed mainly onto the base, and the ceramic envelope should

be maintained below the maximum rated temperature. An air

flow of at least 2.83 m

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.
