The radiation tolerant readout system for srambased neutron detector

Bremsstrahlung gamma radiation and photoneutrons are produced during the operation of high energy linear accelerators. The functionality of electronic devices that are placed inside accelerator tunnels can be jeopardized because of the negative influence of generated radiation. Therefore, a radiation monitoring system able to gauge neutron fluence and gamma dose in real time was constructed. Radiation-sensitive dosimeters cooperate with a readout system. The readout continuously measures both types of radiation and sends quantified data to a main computer. The system is also placed in the tunnel, hence it must be insensitive to radiation or able to tolerate induced malfunctions. A few different readout systems were designed. This work presents the application of different readouts designed using commercial of the shelf (COTS) components. The presented hardware was tested with americium-beryllium neutron source. Finally, the systems were irradiated in a linear accelerator tunnel to estimate their immunity and suitability for a long-term reliable operation in the radioactive field
