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.

NOTES
1. Anode voltage must be command charged and applied for
HEALTH AND SAFETY HAZARDS
e2v technologies hydrogen thyratrons are safe to handle and
operate, provided that the relevant precautions stated herein
are observed. e2v technologies does not accept responsibility
for damage or injury resulting from the use of electronic devices
it produces. Equipment manufacturers and users must ensure
that adequate precautions are taken. Appropriate warning
labels and notices must be provided on equipments
incorporating e2v technologies devices and in operating
manuals.
510 ms. The tube will not operate with DC anode voltage.
2. This rate of rise refers to that part of the leading edge of
the pulse between 10% and 90% of the pulse amplitude.
3. The jitter levels and rate of rise of current specified in this
data sheet for fast rise time generator service can only be
obtained under very carefully controlled conditions. e2v
technologies therefore reserves the right to approve all
equipments in which the tube is used. DC heater power
supplies are needed to achieve the best jitter figures. If
jitter is not critical then an AC transformer can be used.
High Voltage
4. A recommended reservoir voltage is stamped on
each tube. For the fastest switching speed, the
reservoir voltage should be increased to a maximum
value consistent with anode voltage hold-off in the
equipment.
Equipment must be designed so that personnel cannot come
into contact with high voltage circuits. All high voltage circuits
and terminals must be enclosed and fail-safe interlock switches
must be fitted to disconnect the primary power supply and
discharge all high voltage capacitors and other stored charges
before allowing access. Interlock switches must not be
bypassed to allow operation with access doors open.
The reservoir heater supply must be obtained either from
the cathode heater supply or if a separate supply is used it
must be decoupled to avoid damage to the reservoir.
5. The tube must be mounted by means of its mounting
flange.
X-Ray Radiation
All high voltage devices produce X-rays during operation and
may require shielding. The X-ray radiation from hydrogen
thyratrons is usually reduced to a safe level by enclosing the
equipment or shielding the thyratron with at least 1.6 mm
( 1/16 inch) thick steel panels.
6. The peak inverse voltage including spike must not exceed
1.0 kV for the first 25 ms after the anode pulse.
7. For single-shot or low p.r.f. applications this parameter can
exceed 100 kA/ms. The ultimate value which can be
attained depends also to a large extent upon the external
circuit.
Users and equipment manufacturers must check the radiation
level under their maximum operating conditions.
8. Measured with respect to cathode. When grid 1 is pulse
driven, at least the first 0.25 ms of the top of the grid 1
pulse must precede the delayed grid 2 pulse.
9. The tube may be operated with a loaded grid 2 bias voltage
of 0 to 725 V provided that care is taken to ensure that the
peak grid 1 drive current is sufficiently low to prevent triode
firing (tube control by the grid 1 pulse).
10. DC negative bias voltages must not be applied to grid 1.
When grid 1 is pulse driven, the potential of grid 1 may
vary between 710 and +5 V with respect to cathode
potential during the period between the completion of
recovery and the commencement of the succeeding grid
pulse.
11. The time interval between the instant when the unloaded
grid 2 voltage passes cathode potential and the instant
when anode conduction takes place.
12. The drift in delay time over a period from 10 seconds to
10 minutes of high voltage operation.
