A novel, cylindrical geometry, superconducting pion channel has been constructed at Stanford. It can simultaneously deliver up to 60 radially converging pion beams of the same mean momentum but with individually variable momentum spread (0.0-4.3%). Virtually no tuning of the pion beam is required Preliminary tests have demonstrated many of the performance characteristics which facilitate the treatment of selected human tumors.
斯坦福大学建造了一种新型的圆柱形几何结构超导π介子通道。它能够同时输送多达60束具有相同平均动量但动量分散度可单独变化（0.0 - 4.3%）的径向汇聚π介子束。几乎无需对π介子束进行调谐。初步测试已展示出许多有助于治疗特定人类肿瘤的性能特征。
