The factors related to the performance parameters of a Boron-lined proportional counter are discussed in this paper, the approaches and techniques for improving the performance are summarized and analyzed based on the structure design, the manufacture technique and the moderator of the Boron-lined proportional counter. The effects of an enriched 10B and the Boron-lined floor thickness on the detection efficiency are determined, the technical tendency of adding the surface area, the Boron-lined method and the thermostability is illustrated. The Boron-lined proportional counter will be developed in the way of choosing more suitable filling gas, better-developed anode wire mounting technology and Boron-lined technique in the future.
