Abstract

The invention provides a production method for a boron-10 element used for a neutron detector, relates to a production method for an element acting as a neutron detector cathode, and mainly aims at solving problems that existing neutron detectors are high in conductive substrate mass and limited in the number of the captured neutrons. According to the method, a graphite vinyl transparent film is adopted to act as a conductive substrate, boron powder is unformly sprayed on the graphite vinyl transparent conductive film by adopting an electrostatic spraying method and protected by high-purity nitrogen and heated for 2-10h under temperature of 50-150 DEG C, boron powder enters the film through thermal diffusion and entering depth is 0.5-1 micron; and thickness of a boron coating layer is 1-3 microns. Advantages are that the production method is applied to a high-dose radiation area.

Description

Technical field: [0001] The invention relates to a method for the production of an element serving as a cathode for a neutron detector. Background technique: [0002] 10 B+n→ 7 Li+ 4 he [0003] After boron-10 captures a neutron, it becomes a helium particle through reaction. According to this principle, a neutron counter can be made. Neutron counters are used in a wide range of applications, such as radiation monitoring of nuclear waste, and homeland security applications. [0004] In the Chinese patent CN102967875A, J.M. Lustig pointed out that the conductive substrates such as aluminum, nickel, titanium and boron powder are contacted with boron powder at high temperature for a long time, and the boronization of the substrate is realized by thermal diffusion method to prepare the boron coating for capturing neutrons. layers; a conductive substrate and boron coating as the cathode, and a central processing mechanism as the anode, forming a neutron detector. Its disadv...
