Abstract: International audience; For stable operation of the Belle II Silicon Vertex Detector in the future high-luminosity operation of SuperKEKB, we plan to reduce readout data-samples per trigger and to apply hit-selection using hit-time. To realize this plan, we developed novel hit-time estimation methods, one of which achieves the resolution of 2.28 ± 0.04 ns evaluated in the current data acquisition mode. A study using Monte Carlo simulation also confirms that the hit-selection based on this hit-time improves track reconstruction performance.
