Abstract
For use in providing control of a pulsed neutron generator tube and its associated power supplies, the preferred and illustrated embodiment of the control circuit senses the operative condition of the pulsed neutron generator tube by observing external insulating gas pressure of the sealed tube to monitor for a loss of pressure, target current magnitude, pulsing of the ion source, current flow for the replenisher and operation of the high voltage power supply. This system functions as an interlock, thereby enabling operation of the tube if nominal operative conditions are achieved. Conversely, the absence of nominal operative conditions switches the equipment off to protect the tube from damage resulting from malfunction.
