Belle-II VerteX探测器（VXD）的设计目的是提高贝儿探测器的性能，并科普SuperKEKB可达到的前所未有的8× 10 35 cm− 2 s− 1的亮度。需要特别注意监测整个实验期间累积的辐射剂量和瞬时辐射率，以便能够对突然出现的峰值迅速作出反应，从而保护探测器。基于单晶金刚石传感器的辐射监测和束流中止系统目前正在为VXD积极发展。传感器将被放置在交互区域附近的几个关键位置。严重的空间限制要求对传感器进行具有挑战性的远程读取。
Abstract The Belle-II VerteX Detector (VXD) has been designed to improve the performances with respect to Belle and to cope with an unprecedented luminosity of 8× 10 35 cm− 2 s− 1 achievable by the SuperKEKB. Special care is needed to monitor both the radiation dose accumulated throughout the life of the experiment and the instantaneous radiation rate, in order to be able to promptly react to sudden spikes for the purpose of protecting the detectors. A radiation monitoring and beam abort system based on single-crystal diamond sensors is now under an active development for the VXD. The sensors will be placed in several key positions in the vicinity of the interaction region. The severe space limitations require a challenging remote readout of the sensors.
