One of the goals of high energy heavy ion collisions is to study the QCD phase diagram and the properties of the Quark-Gluon Plasma. J-PARC in Japan (a proposed future program) is focusing on the high baryon density region of the phase diagram and also the search of the critical point in the phase transition.
In these heavy ion collisions, charged particle identification is needed. In this abstract we focus on the Time-of-Flight (TOF) detector in order to identify the different particle species. The current proposal is focused to use Multi-Gap Resistive Plate Chambers (MRPC) technology to achieve good timing resolution at J-PARC E-16 experiment. In E-16, 30 ps of timing resolution is required for particle identification.
To achieve good timing resolution, impedance-matched and reflection-suppressed signal transmission is needed. Electromagnetic simulation is the solution for such a pad design, and rigid ground layer is necessary for accurate simulation.
Our main challenge of MRPC is to place rigid ground and sophisticate the pad shape. In this talk, the current R&D focused on these improvements and the results of the status will be presented.
