CX1599
Hydrogen-Filled Ceramic Thyratron
The data to be read in conjunction with the Hydrogen
Thyratron Preamble.
ABRIDGED DATA
Hydrogen-filled tetrode thyratron with ceramic envelope,
featuring extremely low jitter, low anode delay time drift and
high rate of rise of current. A hydrogen reservoir operating
from a separate, variable heater supply is incorporated.
CX1599 is a fast, precise switch originally designed for use in
pulse generators to drive Kerr cells, Pockel cells or spark
chambers. Anode voltage must be command charged and
applied for less than 10 ms. The tube geometry allows it to be
mounted in a coaxial housing in order to minimise the total
circuit inductance.

natural, forced-air or liquid
Where natural cooling is insufficient to maintain the envelope
temperatures below the specified rated values, cooling by
forced-air, or by oil or coolant immersion may be used.
The temperature of the anode terminal and the base, measured
at the points indicated on the outline drawing, must not exceed
the values specified below.
