Abstract
The Belle II experiment operates at the SuperKEKB $e^+ e^-$ energy-asymmetric collider on or near the $\Upsilon(4S)$ resonance energy. The Belle II experiment has completed the Phase 2'' run, in which the Belle II operation without the vertex detector system has been tested. The main focus of the Phase~2 run is on the search for new physics related with dark sector, axion-like particles, etc. with an intermediate luminosity on the way to reach the challenging target. To accomplish these physics goals of Phase~2, a new trigger menu for the single photon and low multiplicity events is essential. With the luminosity design goal, it is crucial to cope with a high trigger rate for data acquisition (DAQ). In this presentation, we describe the DAQ system of Belle II, focusing on the successful commissioning in Phase 2 and the performance of the system.
