The measurement of the K ± production in the Semi-Inclusive Deep Inelastic Scattering (SIDIS) can provide further knowledge about the structure of nucleon, and thus it is purposed in the Solenoidal Large Intensity Device(SoLID) at Jefferson Lab(JLab). In this experiment, the identification of the kaons is planed to be accomplished with the Multi-gap Resistive Plate Chambers(MRPC), and the requirement for the time resolution is around 20 ps. This is very challenging for the present MRPC systems (typical resolution 60 ps), while in this paper, it is proved that the performance can be improved largely if the signal waveform is obtained and analyzed with a neural network method. In a cosmic ray experiment, the time resolution of a 6-gap 0.25mm-thick MRPC reaches 36 ps with this method, and a even better performance is expected with a thinner MRPC.

“…Just like the CBM-ToF, the low resistive silicate glass is employed as the resistive plate to achieve a high rate capability. To better understand the detector's working principles and improve the performance, a standalone simulation framework of the MRPC detector has been built and carried out [86,87]. The energy deposition produced by the passing particles is simulated based on the PAI model [88], which is proved to be effective for very thin absorbers.…”

Multigap Resistive Plate Chambers for Time of Flight Applications

2020

Applied Sciences

With the advantages of high-performance, easy to build and relatively low cost, the multigap resistive plate chamber has been arousing broad interests over the last few decades. It has become a new standard technology for the time of flight system in high energy physics experiments. In this article, we will give a description of the structure and the operating principles of the MRPC detector and focus on reviewing the applications on the time of flight system in several famous experiments. The performances, including time resolution and particle identification, are discussed in detail. Some recent advances and points of view for the future development of the next generation MRPC are also outlined.

“…In the meantime, a Monte Carlo simulation of the detector based on the simulation framework developed in our group [31,32] is carried out. The typical simulation process of the detector is summarized in figure 6.…”

A: A high time resolution Multi-gap Resistive Plate Chamber (MRPC) is proposed for the TOF system of SoLID experiment at Jefferson Lab. Efforts have being devoted to the research of a new MRPC structure, aiming at a time resolution of 20 ps. Two 32-gap MRPCs with 104 µm gap thickness have been developed for the initial test. By using the fast amplifier and waveform digitizer system, the performace of these MRPC detectors is studied using the cosmic rays. Time resolution of the order of 20 ps and efficiency around 95% are obtained. Detector simulations are simultaneously carried out for MRPCs with different structures. Meaningful results and future plans are discussed in detail.
