LHCb实验是为精确测量CP破坏和罕见的美丽和魅力强子衰变而设计的。该实验将升级为无触发系统，以40 MHz的事件速率读出完整的探测器，所有选择算法都在CPU群中执行。升级后的Vertex Locator将是一个混合像素探测器，由VeloPix ASIC读出，具有芯片内零抑制功能。本文将概述该系统以及VELO探测器电子设备的设计，包括前端混合电源、光电转换和配电板。将讨论这些原型的评估结果和进一步的增强技术。
The LHCb Experiment is designed for precision measurements of CP violation and rare decays of beauty and charm hadrons. The experiment will be upgraded to a trigger-less system reading out the full detector at a 40 MHz event rate with all selection algorithms executed in a CPU farm. The upgraded Vertex Locator will be a hybrid pixel detector read out by the VeloPix ASIC with on-chip zero-suppression. The overview of the system and the design of the VELO on-detector electronics that include the front-end hybrid, the opto-conversion and power distribution boards will be summarised. The results from the evaluation of these prototypes and further enhancement techniques will be discussed.
