摘要
详细介绍了一种新型正电子寿命测量装置——快/快符合型正电子寿命谱仪的组成和工作原理,系统地介绍了谱仪的调试方法和调试结果,概述了调试过程中存在的具体问题和解决措施.
Positron annihilation technique has been quickly developed in recent years. Positron lifetime measurement is one of the three main experimental methods of the technique. The paper introduces an advanced positron lifetime measurement apparatus-Fast/Fast Coincidence System, and its installation, testing and improvement. In the end, problems existing in the test and their solutions are described.
