HL-LHC的亮度增加将需要升级后的ATLAS跟踪器中的更多通道，这是由于探测器分割更精细，否则占用率太高。在ATLAS Tracker升级所面临的众多技术挑战中，有一个更有效的电源分配和传感器的高压偏置。当前ATLAS探测器中采用的解决方案为每个传感器使用一个HV导体，这使得在不影响其他传感器的情况下禁用故障传感器变得容易，但是空间限制和材料预算考虑使得这种方法对于升级的探测器来说是不切实际的。为此目的，目前正在研究许多方法，包括使用相同的HV线来偏置几个传感器和合适的HV开关沿着它们的控制电路。沿着最新的测试结果和测量将被描述。
The increased luminosity of the HL-LHC will require more channels in the upgraded ATLAS Tracker, as a result of the finer detector segmentation, stemming from the otherwise too high occupancy. Among the many technological challenges facing the ATLAS Tracker Upgrade there is more an efficient power distribution and HV biasing of the sensors. The solution adopted in the current ATLAS detector uses one HV conductor for each sensor, which makes it easy to disable malfunctioning sensors without affecting the others, but space constraints and material budget considerations renders this approach impractical for the Upgraded detector. A number of approaches, including the use of the same HV line to bias several sensors and suitable HV switches, along with their control circuitry, are currently being investigated for this purpose. The proposed solutions along with latest test results and measurements will be described.
