Description
We are developing TOF and TOF-tracker MRPCs for the J-PARC MARQ experiment and muography applications.
The TOF MRPC will be used as a particle-identification (PID) detector in the MARQ spectrometer at the high-momentum beamline of J-PARC.
In contrast, the TOF-tracker MRPC is being developed as a muon detector providing both position and timing information.
These MRPCs share a common detector structure and front-end electronics.
We have developed new construction techniques, such as a novel high-voltage electrode that can be printed on PET films, gas spacers made from double-sided adhesive tape.
We are also developing a gas-tight sealing system in which only glass plates are sealed.
In addition, we are developing low-noise front-end electronics compatible with triggerless streaming DAQ systems.
In this contribution, we describe the key technologies developed for these MRPC detectors.
