利用AMS-02进行空间反物质和暗物质搜索

Antimatter and Dark Matter search in space with AMS-02

Francesca R. Spada

摘要:

AMS-02是一个星载磁谱仪,用于高精度测量地球附近宇宙射线的成分。AMS-02具有5000平方厘米的大接受能力、来自超导磁体(0.7 T)的强磁场和非常有效的粒子识别,将在TeV区域的宇宙射线测量中提供最高精度。在国际空间站为期三年的任务中,AMS-02将实现对宇宙射线中反氦核存在的十亿分之一的灵敏度,并提供有关暗物质的起源和性质的重要信息。

英文摘要:

AMS-02 is a space-borne magnetic spectrometer designed to measure with very high accuracy the composition of Cosmic Rays near Earth. With a large acceptance of 5000 squared centimeters, an intense magnetic field from a superconducting magnet (0.7 T) and a very efficient particle identification, AMS-02 will provide the highest precision in Cosmic Rays measurements up to the TeV region. During a three-years mission on board of the International Space Station, AMS-02 will achieve a sensitivity to the existence of anti-Helium nuclei in the Cosmic Rays of one part in a billion, as well as provide important information on the origin and nature of the Dark Matter.
