ATLAS SCT（半导体跟踪器）包括安装在四个长度为 1.5m、直径达 1m 的同心桶上的 2112 个桶模块，以及由桶两端的一系列 9 个轮子支撑的 1976 个端盖模块。每个模块均由其自己独立的浮动低压和高压电源供电，并以探测器屏蔽处的接地为参考。相应地，每个模块都有自己独特的电缆链一直回到服务洞穴。本演示概述了 SCT 电源系统的结构和规格，包括高级控制软件和操作模型。 I. 系统要求 尽管筒体和端盖区域中使用的探测器模块在几何形状上非常不同，但它们在电气方面非常相似。为每个模块提供单一参考电位的愿望导致每个模块 [1] 采用单根多线屏蔽电缆，因此在每个电源 (PS) 箱中将浮动、可编程低压 (LV) 和高压 (HV) 电源通道放在一起。电压 [V] 电流 [mA] 参数 最小值典型值。最大限度。典型值。最大限度。电源电压 0.0 3.5 5.1 90
The ATLAS SCT (semiconductor tracker) comprises 2112 barrel modules mounted on four concentric barrels of length 1.5m and up to 1m diameter, and 1976 endcap modules supported by a series of 9 wheels at each end of the barrel. Each module is powered by its own independent, floating low and high voltage power supplies, referenced to ground at the detector shield. Correspondingly, each module has its own distinct cable chain all the way back to the service cavern. This presentation outlines the structure and specification of the SCT Power Supply System, including the high level control software and operational model. I. SYSTEM REQUIREMENTS Although the detector modules used in the barrel and endcap regions are geometrically very different, they are electrically very similar. The desire to provide each module with a single reference potential resulted in the adoption of a single, multi-wire, shielded cable to each module [1] and hence in the location of floating, programmable Low Voltage (LV) and High Voltage (HV) power supply channels together in each Power Supply (PS) crate.
