Abstract
A pulsed neutron system including an accelerator tube having a target, an ionization section, and a replenisher section for supplying accelerator gas. An ionization circuit includes means for applying repetitive ionization pulses to the ionization section. The current in the ionization circuit is monitored in order to detect incremental current events occurring during the ionization pulses. A count rate function is produced which is representative of the frequency of the incremental current events. The power supplied to the replenisher section is controlled in response to the count rate function. The replenisher power is increased in response to a decrease in the count rate function and decreased in response to an increase in the count rate function.
