Abstract

Lithium-drifted silicon detectors were used to investigate the components of the pion beam at the Los Alamos Meson Physics Facility. The components of the incoming beam are about 5% electrons, 10% muons, and 85% pions. Pulse spectra of the incoming beam and of the "stars" produced by the pions were obtained in a phantom. The analysis of the spectra into different LET components showing where pions are most effective is presented.

摘要

锂漂移硅探测器被用于研究洛斯阿拉莫斯介子物理设施中π介子束的成分。入射束的成分大约是5%的电子、10%的μ子和85%的π介子。在一个模体中获取了入射束和由π介子产生的“星”的脉冲光谱。给出了将光谱分析为不同传能线密度成分的结果，显示了π介子最有效的位置。
