加速器质谱(AMS)测量中的粒子鉴别探测器

The particle identification detectors in accelerator mass spectrometry

描述了中国原子能科学研究院AMS测量中使用的飞行时间探测器、多阳极电离室、Bragg探测器、入射离子X射线探测器以及充气飞行时间探测器。通过它们可以获得粒子的飞行时间、部分能量和总能量,从而达到粒子鉴别的目的。介绍了采用这些探测器在HI-13串列AMS系统上做的相关工作以及取得成果。

The TOF, multi-anode gas ionization chamber, Bragg and X-ray detectors in accelerator mass spectrometry are described. The time, ΔE and E signals obtained from these detectors have been used for particle identification. The applications and the experimental results by using these detector systems in HI-13 tandem AMS facility have been introduced in details.
