Description
The μRGroove is a novel micro-pattern gaseous detector with a resistive micro-groove amplification structure. A cylindrical μRGroove (c-μRGroove) detector was developed for inner tracking application in future electron-position collider experiments, such as the Super Tau-Charm Facility. Its spatial resolution in strong magnetic field is a key figure of merit for evaluating tracking performance. Beam tests were carried out of the detector at the CERN SPS H4 to characterize its performance in magnetic field. The c-μRGroove detector operated stably in a 1 T magnetic field. A spatial resolution better than 130 μm and a detection efficiency exceeding 95% were achieved for the detector in the magnetic field with the micro-TPC reconstruction algorithm. A detailed simulation with full detector response was performed to reproduce the test beam results. The detector design was optimized based on the simulation. The optimization indicated that increasing the effective gas gain, reducing avalanche gain fluctuations, and improving the measurement precision of the T₀ timing can further enhance the position reconstruction performance of the detector. These results demonstrate that the c-μRGroove detector is a promising solution for inner tracking in future electron-position collider experiments.
