“…The dark current of SMRPC stays at a low value during the whole test, which shows that our detector works at a low noise level. Since the temperature usually influences the detector working performance dramatically [14], the temperature in our test is recorded and it didn't show any significant fluctuation. As shown in figure 7, we tested the SMRPC for one month at 0.5 ml/min gas flow and the detector efficiency is usually higher than 92%.…”

A: A muon tomography system named Tsinghua University cosmic ray Muon tomography (TUMUTY) facility based on Multi-Gap Resistive Plate Chamber (MRPC) has been built in Tsinghua University in 2012. Our research is focused on developing a muon non destructive testing system that will be used in homeland security operations such as custom inspections, airport security and so on. The gases normally used to operate MRPCs (C 2 F 4 H 2 , SF 6 and i-C 4 H 10 .) have a high global warming potential. Eco-gas is a choice to solve this problem, but it will greatly increase the overall cost of the system. On the other hand, we can also reduce the greenhouse pollution by lowering the airflow to the chamber. In this paper, a sealed MRPC prototype filled only with C 2 F 4 H 2 has been designed and studied. The prototype has a sensitive area of 500 mm • 500 mm, and it can work very well at an extremely low gas flow of 0.5 ml/min. Moreover, we also studied the performance of the detector under a mode without gas exchange. The result shows that the detector can work for more than 60 hours without gas exchange. Under this mode, the average gas flow of the detector reduces to 0.05 ml/min.

“…Thus, the idea of "effective voltage" V e f f is given to describe the relationship V e f f = V app × T T re f × P re f P (10) where V app is the applied high voltage, T and P are the actual temperature and pressure, T re f and P re f are the reference values. The efficiency versus the high voltage at different temperatures [109] is reported in Figure 17b. The working voltage varies at different temperatures.…”

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.

“…A schematic diagram of the system used to study temperature effects on MRPC performance is shown in figure 6. A cosmic ray test system was placed in a temperature-controlled box [22]. The performance of the MRPC was studied using both the so-called the "standard" gas mixture (Freon/SF 6 /isobutane:90%;5%;5%) and pure Freon gas…”

Muon tomography is an innovative high-Z material detection technology developed in recent years. The most crucial part of this technology is the high position resolution detectors used for the muon track reconstruction. Multi-Gap Resistive Plate Chambers (MRPCs in the following) are gaseous detectors first developed at CERN in middle 1990s. Considering their characteristics in terms of high efficiency, low cost, robust structure, and excellent position resolution, MRPC became the detector of choice for the TUMUTY (Tsinghua University cosmic ray muon tomography facility) system built in 2012. This paper features a summary about the latest developments on MRPC technology for muon tomography. After the success of the TUMUTY prototype, researches were carried out on larger sensitive area position resolution MRPCs with 2-D readout, and on environment-friendly sealed MRPCs (SMRPC) for industrial applications and future muon tomography systems. It was studied how encoding readout methods and external environment influence the performance of MRPC detectors. Also, an MRPC simulation frame and new data processing methods were both developed, which have provided useful information on optimal design of the future position resolution MRPCs and muon tracking systems.
