报道第三代北京谱仪漂移室(BESIII DC)定位子的结构设计?制作生产及其基本性能。定位子是漂移室的精密部件,专用性强,结构精度高。产品按国标GB2829-2003,质量水平II级验收。性能检验中高压绝缘性分长?中和短三种周期进行;湿度响应在自然变化和人工控制两种情况下观察;抗老化能力通过模拟老化实验前后性能比较得出。
Report the third generation of Beijing spectrometer drift chamber (BESIII DC) structural design of the locator? Production and its basic performance. The locator is a precise component of the drift chamber, strong specificity and high structural accuracy. Products by national standard GB2829-2003, quality level II acceptance. Performance tests in the high voltage insulation in the long? Neutralization and short cycle of three; humidity response in the natural changes and artificial control of two cases observed; anti-aging ability by simulating the aging performance comparison before and after the experiment.
