Low-Noise Detector of Minimally Ionizing Particles Based on Microсhannel Plates

Detection of minimally ionizing particles in rare processes requires the creation of fast detectors with high efficiency and low noise levels. For a device consisting of two MCP assemblies, the possibility of increasing the detection efficiency of minimally ionizing particles (~95%) with a simultaneous increase in the signal-to-background ratio and with high resistance to electromagnetic interference is shown. These results indicate that dual-MCP architecture offers a promising approach for high-precision, low-noise particle detection in challenging experimental environments.
