Abstract

The Belle-II experiment at the SuperKEKB aims to achieve a target instantaneous luminosity of 8×1035cm-2s-1. To cope with the design luminosity, the sub-detectors and the level-1 trigger system are required to be upgraded. The central drift chamber in the Belle-II detector which plays a primary role in the track reconstruction of charged particles is a multi-wire drift chamber with 14,336 channels. The central drift chamber-based trigger is responsible for distinguishing specific types of physics, which is based on fast track reconstruction. The fabrication of a small prototype of the central drift chamber and the development process of the central drift chamber-based trigger system are described.
