摘要

Muon imaging technology is an innovative imaging technique that can be applied in volcano imaging, heavy nuclear material detection, and archaeological research. The Micromegas detector is a promising choice for muon imaging due to its high spatial resolution and large area. However, the large number of readout channels poses a challenge for electronics. A highly integrated front-end electronics was designed and implemented for the multi-channel readout requirements of Micromegas detectors. The electronics use a current-based readout chip, ADAS1128, which integrates 128 current amplifiers for multi-channel charge measurement. The performance of the front-end electronics was first tested under floating input conditions. Then, the energy resolution was obtained with a radioactive source test. Finally, a muon image system was set up to verify the imaging capacity of Micromegas detectors. Test results indicate that for muons with incident angles from 0 to 5 degrees, the spatial resolution of the system is better than 200 μ m. The muon image system can reconstruct the boundaries for objects with a size of 2 cm.
