Exploration of Imaging for Visible Light and Infrared Prototype Monitor of Reactor Cabin under Nuclear Radiation

The nuclear radiation environment in the reactor cabin is simulated by neutrons and gamma rays engendered by the deuteron beam bombarding thick Be target in the 4.5 MV Van de Graaff electrostatic accelerator at Peking University. In this environment, the imaging characteristics of CCD visible light imaging hardware and thermal-sense resistor infrared imaging hardware of the visible light and infrared prototype monitor of the reactor cabin is tested. At the same time, the imaging capability of RUIXING CMOS and CCD imaging hardware is also tested. The experiment results indicate: the anti-radiation capability of the thermal-sense resistor infrared imaging hardware excels the CCD and CMOS imaging hardware and adapts to the nuclear radiation environment in the reactor cabin; the anti-radiation capability of CMOS excels that of CCD and should be used as the visible light imaging hardware for the monitor in the reactor cabin; in order to improve the working reliability, more reinforcement of the anti-radiation should be taken on the control circuit.
