Abstract
The operating regimes of ion sources with a magnetically isolated discharge under conditions of packet-pulse power are experimentally studied. Ion sources with the magnetically isolated discharge are widely used in portable pulsed neutron generators in equipment for geophysical exploration of wells. The efficiency and performance of the logging equipment is largely determined by the amplitude–time characteristics of neutron fluxes, which depend on the magnetic field, anode voltage pulses, composition, and gas pressure. Post-discharge processes occurring in pauses between supply voltage pulses in the interelectrode gap affect the conditions for the re-ignition of the discharge and the stability of the characteristics of the generated electron flows. The results obtained show that gaps in the operation of the ion source occur in the initial part of the pulse packet. At the same time, their number increases with a decrease in the discharge current. The pulses of ion flows at the first actuations of the cell have a shorter duration due to the prolongation of the discharge formation processes.
