提出了一种利用重离子环成像切伦科夫探测器（HIRICH）进行速度测量的相对论性重离子粒子识别新技术。HIRICH的特点是采用薄的液态或固态辐射体、近距离聚焦几何结构和带有CsI光子转换器的快速气体光子探测器。β≃0.85的Ru44+粒子的速度分辨率达到Δβ/β=8×10−4（fwhm）。介绍了探测器的设计及其在GSI-Darmstadt重离子反应研究中的性能。
A novel technique for particle identification of relativistic heavy ions has been developed utilizing a Heavy-Ion Ring Imaging Cherenkov detector (HIRICH) for velocity measurement. The HIRICH is characterized by a thin liquid or solid state radiator, a proximity focusing geometry and a fast gaseous photon detector with CsI photon converter. A velocity resolution of Δβ/β=8×10−4(fwhm) has been measured for Ru44+particles of β≃0.85. The detector design and the performance in heavy-ion reaction studies at the GSI-Darmstadt are presented.
