宇宙射线μ成像探测器由大约3000根单根精密漂移管组成,本研究取得单根探测器的研制成功,创建了精密漂移管生产、装配平台,完成精密漂移管单管宇宙射线μ测量实验。经调研和实验,确定精密漂移管的设计要求和技术指标关键为:1)密封漂移管,保证3个大气压气体无泄漏;2)在阳极和阴极间设计高绝缘,设计保护环,确保电压高达4000V时,阳极 The cosmic ray μ imaging detector consists of approximately 3000 single precision drift tubes. In this study, we succeeded in developing a single detector and created a precise drifting tube production and assembly platform to complete the single-tube cosmic ray measurement experiments of precision drift tubes. After investigation and experiment, the key points to determine the design requirements and technical specifications of the precision drift tube are: 1) Seal the drift tube to ensure no leakage of 3 atmospheres; 2) Design a high insulation between the anode and cathode to design a guard ring to ensure that the voltage is up to 4000V when the anode
