“…The spatial resolution can be obtained from the deviation between hit position and reconstructed position. The X-ray hit position is re-constructed by the charge center-of-gravity method [14]. where Q i is the charge induced on the readout strip after the electronics pre-amplifier, and x is the reconstructed position.…”

A: Muon tomography system built by 2-D readout high spatial resolution Multi-gap Resistive Plate Chamber (MRPC) detector is a project in Tsinghua University. In 2013, we had developed a prototype of muon tomography system named TUMUTY, now we try to develop larger sensitive area and smarter structure MRPC detector to upgrade the system to a car detection system, which is used to detect high Z metal hidden in cars or other objects. For the system, 2 layers ×3 detectors are needed to get the incident particle's track, and the setting is the same for the outgoing track. Therefore, there will four layers containing twelve detectors in total, and its detection area will reach 1 × 3 m 2 . An encoding readout method is suggested to minimize the number of the readout electronics, which reduces the complexity and the cost of the system. In this paper, we measured the performance of 12 MRPCs used for the system.

“…In the car inspection project, the structure of the MRPCs is the same as the TUMUTY MRPC, which has 6 gaps, each 0.25 mm thick, but with a larger sensitive area of 1060 mm × 1060 mm [18,19]. Moreover, this detector features two-dimensional readout, as shown in figure 4.…”

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.

“…The structure of the large scale and high spatial resolution two-dimensional readout MRPC prototype is presented in figure 1 [14]. The prototype is composed of two parallel resistive plate electrodes with six gas gaps divided by five resistive floating glasses whose bulk resistivity is about 10 12 Ω•cm.…”

Performance study of large area encoding readout MRPC

A: Muon tomography system built by the 2-D readout high spatial resolution Multi-gap Resistive Plate Chamber (MRPC) detector is a project of Tsinghua University. An encoding readout method based on the fine-fine configuration has been used to minimize the number of the readout electronic channels resulting in reducing the complexity and the cost of the system. In this paper, we provide a systematic comparison of the MRPC detector performance with and without fine-fine encoding readout. Our results suggest that the application of the fine-fine encoding readout leads us to achieve a detecting system with slightly worse spatial resolution but dramatically reduce the number of electronic channels.
