Abstract

The invention provides a small-diameter radio-frequency drive deuterium-deuterium neutron pipe, which is characterized in that: a plasma generator, a storage unit and a gate electrode are arranged at one side in a shell; an accelerating electrode, a target and a cathode electrode are arranged at the other side in the shell; the accelerating electrode and the cathode electrode are arranged in the target; one end of the cathode electrode is fixedly connected with the accelerating electrode, and the other end of the cathode electrode is fixedly connected with an external binding post II; an external binding post II is fixedly connected to one end of the target; the storage unit is arranged at the inner side of a plasma generator; the gate electrode is arranged at the outer side of the plasma generator; the plasma generator, the storage unit and the gate electrode are respectively fixedly connected with an external binding post I; and an insulation layer is fixedly bonded on the inner wall of the shell. The small-diameter radio-frequency drive deuterium-deuterium neutron pipe disclosed by the invention has a simple structure, the minimum diameter up to 22mm and wide application field; the energy of generated neutrons is 2.45MeV; and the small-diameter radio-frequency drive deuterium-deuterium neutron pipe is particularly suitable for the field of neutron-neutron logging, neutron-capture energy spectrum logging and other low-energy neutron application.

Description

technical field [0001] The invention relates to a small-diameter radio-frequency driven deuterium-deuterium neutron tube, which belongs to the technical field of neutron tubes. Background technique [0002] At present, electronically controlled neutron generation technology is widely used in basic scientific research, national defense engineering, industry, agriculture, medicine and other fields. Due to the continuous improvement of environmental protection requirements in the logging industry, the development direction of neutron logging-neutron logging, neutron-gamma logging and neutron-gamma spectrum logging technology is to use electronically controlled pulsed neutron sources. Therefore, small-diameter neutron generators have been used more and more in the field of petroleum logging. However, domestic logging instruments generally use accelerator-type deuterium-tritium reaction neutron tubes, and the neutron yield is about 1×10 8 , due to the use of commercial targets,...
