High-Energy Cosmic Rays

This experiment was designed to determine the isotopic abundance in the primary cosmic rays for hydrogren through nickel. The instrument used a 10-element solid-state particle telescope consisting of lithium-drifted silicon detectors. Energy ranges measured ran from approximately 20 to approximately 500 MeV/nucleon. The direction of incident nuclei was obtained from a six-plane drift chamber with 2-deg resolution.

本实验旨在确定从氢至镍的初级宇宙射线中的同位素丰度。实验所采用的仪器为一台由锂漂移硅探测器构成的十元素固态粒子望远镜。测量的能量范围大约在20至500 MeV/核子之间。通过具有2度分辨率的六平面漂移室，获得了入射核的方向。
