driven, the last 0.25 ms of the top of the grid 1 pulse must
overlap the corresponding first 0.25 ms of the top of the
delayed grid 2 pulse. (See schematic diagram, page 5).
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.

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.
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.
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
(
Users and equipment manufacturers must check the radiation
level under their maximum operating conditions.
