WELL PULSE NEUTRON GENERATOR Russian patent published in 2009 - IPC G21G4/02 

FIELD: physics, measurements.

SUBSTANCE: application: for performance of geophysical survey of wells by pulse neutron methods. All elements of electric power supply circuit of vacuum neutron tube are made in the form of revolution solids with central holes, are connected to each other mechanically and electrically with the help of threaded electric contacts with central openings, and with vacuum neutron tube - via cup-like threaded bushes with central and side openings, installed on target and anode of vacuum neutron tube, vacuum neutron tube and electric power supply circuit are placed into hollow thin-walled cylinder with external diametre less then internal diametre of leak-tight body, between external wall of thin-walled cylinder and internal wall of leak-tight body there is an external cavity filled with liquid dielectric, communicated with internal cavity created by central openings in cooled elements of electric power supply circuit of vacuum neutron tube.

EFFECT: increased resource of neutron generator operation at high ambient temperature.
