The SPiRIT Time Projection Chamber (TPC) was designed and constructed to perform the experiments for the constraints of the symmetry term of the Nuclear Equation of State. The state-of-art readout electronics, GET readout system, was employed as the readout system for SPiRIT-TPC 12k readout pads.
In the spring of 2016, first campaign of heavy ion collision experiments was performed at RIKEN-RIBF. In this experiment, ~10kHz Sn isotope beams of 270 MeV/u incident energy were used as projectile. I will present the overview of SPiRIT-TPC+GET system, its in-beam performance, and recent result of heavy ion collision experiments in terms of detector technology mainly.
