The Belle II experiment is constructed at the KEK High Energy Accelerator Research Organization in Japan. Due to the high luminosity of the beam, a trigger that effectively rejects beam-induced background is required. For this purpose, a level-1 trigger board with field-programmable gate arrays and high speed optical transceivers is developed for the central drift chamber trigger readout. Utilizing this hardware, we develop our algorithms, which find segments of charged particle trajectories using information of the central drift chamber.

Belle II实验中基于中央漂移室的1级触发系统的轨道段查找器的开发

Belle II实验是在日本的KEK高能加速器研究组织中进行的。由于光束的高发光度，因此需要一种能够有效抑制光束引起的背景的触发器。为此，开发了具有现场可编程门阵列和高速光收发器的1级触发板，用于中央漂移室触发读数。利用此硬件，我们开发了算法，该算法使用中央漂移室的信息找到带电粒子轨迹的片段。
