METHOD FOR OPERATING A PULSED NEUTRON GENERATOR TUBE WHICH EXTENDS THE LIFETIME OF A CATHODE
摘要
A method for operating a pulsed neutron generator including an ionizer with an electron emitting cathode and a grid wherein the cathode and grid are disposed in a sealed chamber. At least one of the following is applicable to the ionizer; a distance between the cathode and the grid, a cathode current and/or a potential on the grid are selected such that the ionizer operates at most about one-half the space charge limited current for a grid current selected to provide a predetermined amount of neutron production.
