摘要
小单元漂移室具有漂移电子扩散小、空间分辨好等特点 ,因而在北京谱仪的升级改造中被采用 .利用漂移室模拟程序GARFIELD7等进行了BES Ⅲ主漂移室对带电粒子响应的MonteCarlo模拟 .据此得到主漂移室输出信号的特点 ,为其读出电子学系统的设计提供了较为准确的理论依据 .
Small cell drift chamber is adopted in the design of BESⅢ-the upgrade version of the BES detector, for its lower electron diffusion and better spatial resolution. We did Monte Carlo study for BES-Ⅲ drift chamber using GARFIELD7, and got the characteristics of the output signals of the sense wires. This become the theoretical basis for the design of drift chamber readout electronics.
