| Zusammenfassung |
| Resistive plate chambers (RPCs) are widely used in high energy physics for
both tracking and triggering purposes, due to their excellent time resolution,
rate capability, and good spatial resolution. 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. The required spatial
granularity is achieved by using 330 readout strips per RPC with 1.5 mm pitch.
The RPCs have shown an efficiency above 99% and an estimated intrinsic resolution
below 1.1 mm. Due to these qualities, RPCs serve as excellent candidates for usage
in volcano radiography. |
