“…They obtained a position resolution around 500 μm [12]. Li Q, A. Blanco, Ye Jin also performed detailed studies on the position resolution of RPC detectors [13][14][15]. Their results prove that the RPCs can be usefully applied for muon tomography.…”

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.

“…We used a pair of PCB pickup panels, whose strip pitches are 6 mm (5 mm wide) and 4 mm (3 mm wide), while deploying the same experimental set up which was shown in figure 2 the trigger coincidence posed challenge with the pickup panels of 4 mm pitch and the cosmic trigger rates as expected, were found to be very low in this case. Here too we used the same technique of obtaining the incident position of a cosmic ray muon by fitting the charge dispersion with two Gaussian functions as discussed earlier [12]. The standard deviation of the Gaussian distribution of the narrower width is considered as the position resolution of the RPC detector under study [13].…”

As part of detailed optimization studies on Resistive Plate Chambers (RPCs) to be deployed in huge numbers in the INO-ICAL experiment, effects of integration time on the dispersion of the induced charge as well as position resolution of a prototype RPC was studied. Two, G10 based pickup panels of strip widths 5 mm and 3 mm were used in these studies. A double Gaussian function was used to fit the dispersion of the induced charge on the strips due to passage of cosmic ray muons through the RPC.

“…Typically RPCs are used to provide trigger and timing signatures while the spatial information they obtain is complemented by more accurate detectors. However, it has been shown that a spatial resolution better than 1 mm [4] can be achieved with specifically designed RPCs. Simulation studies [5] suggest that this resolution would be adequate for Muon Scattering Tomography (MST), in which cosmic muons are tracked before and after they penetrate a target volume (see figure 1).…”

Resistive Plate Chambers (RPCs) are widely used in high energy physics for both tracking and triggering purposes. They have good time resolution and with finely segmented readout can also give a spatial resolution of better than 1 mm. RPCs can be produced cost-effectively on large scales, are of rugged build, and have excellent detection efficiency for charged particles. Our group has successfully built a Muon Scattering Tomography (MST) prototype, using 12 RPCs to obtain tracking information of muons going through a target volume of ∼ 50 cm × 50 cm × 70 cm, reconstructing both the incoming and outgoing muon tracks. We describe a readout system for fine-pitch RPCs using MAROC3 readout chips capable of scaling to a large system.
