与向未来的大规模检测器系统供应电力相关的工程挑战有据可查。我们的社区仍在积极研究两种选择，即串行供电和使用DC-DC转换器。虽然在细节上有明显的不同，但两者都有可能提高供电系统的效率。ATLAS升级条带跟踪器社区已经使用ABCN-25 ASIC构建了两个演示平台，每个平台包括四个硅条探测器模块。第一个stavelet是串联供电的，使用集成到ABCN-25芯片中的分流晶体管来保持所需的工作电压，并提供恒定的电源电流，第二个stavelet使用由CERN集团提供的STV-10 DC-DC转换器。虽然详细的测试计划将继续在欧洲核子研究中心，结果从stavelet测试在RAL在这里介绍。
The engineering challenges related to the supply of electrical power to future large scale detector systems are well documented. Two options remain under active study in our community, namely serial powering and the use of DC-DC converters. Whilst clearly different in detail, both have the potential to increase the efficiency of the powering system.The ATLAS Upgrade Strip Tracker Community has constructed two demonstrator stavelets using the ABCN-25 ASIC, each comprising four silicon strip detector modules. The first stavelet is serially powered, using shunt transistors integrated into the ABCN-25 chip to maintain the required operating voltage given a constant supply current, and the second stavelet uses STV-10 DC-DC converters provided by the CERN group. Although the detailed test programme shall continue at CERN, results from stavelet tests made at RAL are presented here.
