Abstract: 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. © Pleiades Publishing, Ltd. 2025.
