Neutron tube structure for bidirectionally leading out Penning ion source

Abstract

A neutron tube structure for bidirectionally leading out a Penning ion source comprises a shell and an anode cylinder packaged in the shell, cathodes are arranged on the two sides of the anode cylinder respectively, the anode cylinder and the cathodes are jointly embedded in one side of a ceramic cylinder, the other side of the ceramic cylinder is connected with one side of a magnetic ring, the other side of the magnetic ring is provided with an inlet side of a Faraday cylinder, the outlet side of the Faraday cylinder is connected with the inner side of a target electrode insulator, a target electrode is embedded in the Faraday cylinder and on the inner side of the target electrode insulator, and the outer side of the target electrode insulator is attached to the inner wall of the shell; the voltage of the anode cylinder is increased externally, electrons emitted from the cathodes and gas in the anode cylinder are ionized under the combined action of a magnetic field and an electric field, generated ions are led out of holes in the two sides respectively, and the led-out ions are accelerated through Faraday cylinders on the two sides and then bombard a target, and thus neutrons are generated through reaction. The neutron tube structure improves the neutron yield, prolongs the service life of the neutron tube, improves the utilization rate of the neutron tube, and has the advantages of simple structure, convenience in operation, high efficiency and practicability.

Description

Technical field [0001] The present invention relates to the field of neutron tube, and more particularly to a neutron structure of a bidirectional extraction of Pan Ning ion source. Background technique [0002] Neutronis is widely used in actual production, mainly in related fields such as petroleum logging, uranium depression, using Panning ion source design of neutron logging to greatly improve the utilization of oil fields. At the same time, the research and development of high yields and long-lived neutron tubes is also in line with the development strategy of my country's current energy conservation and emission reduction. However, traditional neutron can only lead to Panning ion sources in a single direction, low output, low utensil use rate, and related industries have been subject to foreign technology monopoly. How to guarantee a higher lead-out beam current at a smaller structure size, using limited space to maximize the maximum utilization rate, is the key to the deve...
