多丝正比室视差效应改善方法
A method to reduce the parallax error of multiwire proportional chambers
摘要
Abstract
An method the reduce the parallax error of multi-wire proportional chambers (MWPCs) was introduced. The principle of the parallax error reduction is to divide the electrode planes of the detector into a series of small units, and the potential of each unit was set according to its distance to the sample position. Calculation shows that the method can significantly reduce the parallax error of MWPCs, and almost not deteriorate of the detector's primary electron collection efficiency and gain uniformity of the anode plane.关键词
