AMS-RICH实验的原型

A prototype for the AMS-RICH experiment

G. Boudoul

摘要:

AMS光谱仪将于2005年安装在国际空间站上。在第一个版本的仪器的其他改进中,将增加一个环形成像切伦科夫探测器(RICH),应该为宇宙射线物理学打开一个新的窗口,允许同位素分离高达A = 25之间的1和10 GeV/c和元素识别高达Z = 25之间的阈值和1 TeV/c/核子。它还应有助于AMS所需的高水平冗余和拒绝效率的反相粒子。第二代原型已经运行了几个月:架构和第一个结果。

英文摘要:

The AMS spectrometer will be installed on the International Space Station in 2005. Among other improvements over the first version of the instrument, a ring imaging Cherenkov detector (RICH) will be added and should open a new window for cosmic-ray physics, allowing isotope separation up to A = 25 between 1 and 10 GeV/c and element identification up to Z = 25 between threshold and 1 TeV/c/nucleon. It should also contribute to the high level of redundancy required for AMS and reject efficiency albedo particles. A second generation prototype has been operated for a few months : the architecture and the first results are presented.
