The detector consists of two layers of LSO crystals and a position sensitive photomultiplier tube .

这个探测器是由两层氧正硅酸镥晶体晶体和位置灵敏型光电倍增管组成。

As ICCD device costs high, based on analysis of existing photoelectric detector, we choose photomultiplier tube as a substitute for the principle verification experiment.

由于IC CD器件的成本较高，本论文设计了用光电倍增管进行增益调制的原理验证性实验。

The CCD detector was used to take place of the photomultiplier which was widely used as the optical-electrical converter, and the fast analysis of the spectrum was realized by incorporating a grating.

用CCD检测仪取代了常用的光电转换器件——光电倍增管，通过与光栅结合实现了光谱的快速分析。
