Outline of Final Research Achievements

We developed a high resolution time of flight detector as a next generation's Time-of-Flight (TOF) detector, which can be used for a high baryon density matter search. We performed the electromagnetic field simulation for this particular type of Multi-gap Resistive Plate Chamber (MRPC), and optimized the readout pad shape, and confirmed by the measurements that a new design of MRPC performed as expected. We have also developed a new type of MRPC, in which the real ground is in place, and we successfully read out the signal. We tested various type of MPRC with the beams at ELPH facility at Tohoku University, and we evaluated the best detector design for the MRPC TOF with high timing resolution.
