Abstract
The SπRIT Time Projection Chamber (TPC) was constructed at Michigan State University in the U.S.A. and transported to the Radioactive Isotope Beam Factory at RIKEN in Japan. In October 2015, the SπRIT TPC was commissioned with 200 AMeV 79Se beams outside the SAMURAI dipole magnet. The experimental setup consists of the SπRIT TPC, a Multiplicity Trigger Array, a KATANA array, and a Active Veto array. The TPC is fully equipped with a newly-developed read-out electronics system, GET electronics. The trigger logic to select events of the TPC based on the ancillary detectors was tested. The analysis software, SpiRITROOT, was developed to analyze the SπRIT TPC data to determine the best trigger logic for upcoming experiments.
