    Abstract

    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.
