BOREHOLE PULSE NEUTRON GENERATOR Russian patent published in 2015 - IPC G21G4/02 

FIELD: electricity.

SUBSTANCE: in borehole pulse neutron generator the transformers (2) and (3) are filled with a compound with the dielectric permeability decreasing with temperature rise, the condensers (4), (6) and (7) are filled with the compound with the dielectric permeability increasing with temperature rise. The temperature compensator includes the rubber membrane (13) placed in the housing (9) of the compensator and dividing the compensator into two cavities one of which is connected to liquid dielectric, and another one is filled with neutral gas under pressure.

EFFECT: stabilisation of neutron flow in the wide range of temperatures, reduction of dimensions and weight.
