TPX3 radiation network

AbstraktAbstract

This functional sample represents a distributed, scalable detector network based on Timepix3-equipped nodes, designed for continuous radiation monitoring of existing and newly established nuclear sources and workplaces. It employs a compact solution with robust, easily mountable housing for the Katherine readout and detector assembly mounted on the chipboard, incorporating one of four sensor types (CdTe or Si with different thicknesses). Silicon sensors are equipped with neutron converters. All detectors have been calibrated, including characterization of their neutron response via neutron capture in a ⁶LiF converter and via recoil protons generated in a polyethylene converter. The network architecture also addresses communication between individual nodes and overall system integration, enabling reliable data transfer and centralized data collection. The system is currently operational, with installations at the premises of Charles University, Czech Technical University in Prague, VSB – Technical University of Ostrava, and the University of West Bohemia in Pilsen, where it continuously records and stores radiation field characteristics and composition. All the data are also being centrally stored on the CTU-IEAP server. The presented network demonstrates a scalable and versatile approach to radiation monitoring and can be extended to additional sites, including nuclear engineering facilities. It therefore represents a valuable tool for enhancing radiation safety and improving the understanding of radiation environments in both research and operational contexts.
