为了研制氖闪光管探测仪,作者先后制作了两种不同气压、不同管径的氖闪光管。同时还设计制作了氖管工作所必须的高压脉冲系统。本文叙述了氖闪光管探测仪的制作、结构以及探测效率与高压脉冲幅度的关系。脉冲延迟时间对效率的影响也作了初步探讨。结果表明,氖闪光管的效率与脉冲参数有密切关系。通过实验选择恰当的高压脉冲幅度及脉冲延迟时间是保证探测仪有高效率和低假闪光率的重要因素。
In order to develop neon flash tube detector, the author has produced two different pressure, different diameter neon flash tube. At the same time also designed and manufactured a neon tube work must be high-voltage pulse system. This article describes the neon flash tube detector production, structure and detection efficiency and high pressure pulse amplitude. The effect of pulse delay time on efficiency is also discussed. The results show that the efficiency of neon flash tube is closely related to the pulse parameters. Selecting the appropriate high-voltage pulse amplitude and pulse delay time through experiments is an important factor to ensure that the detector has high efficiency and low false flash rate.
