英文摘要International Thermonuclear Experimental Reactor radial X-ray camera is designed to measure the poloidal profile of the plasma X-ray emission with high spatial and temporal resolutions and will be installed inside equatorial port 12. Due to the harsh environment of neutron and gamma radiations, nuclear radiation hardness of many components has to be considered in design and test, including silicon detector array, electronics, and cabling. As for electronics put in a port cell, a preliminary design of highly integrated preamplifier and program controllable midamplifier has been completed, and many tests have been done to investigate the radiation hardness performance of the amplifiers together with detectors. In the Cf-252 neutron test with flux of similar to 2.23 x 10(3) n.cm(-2).s(-1) and fluence greater than 1.0 x 10(10) n.cm(-2), there was no performance degradation in detector and preamplifier. In the Co-60 gamma test with a dose rate of 0.5 Gy.min(-1) and an accumulated dose of 200 Gy, the performance change was not found in preamplifier and midamplifier except for some radiation damage to the power module in the board of preamplifier. In the following accelerator neutron test where the neutron flux is similar to 5 x 10(7) n.cm(-2).s(-1) and neutron fluence is 2 x 10(12) n.cm(-2), the functional problem was not found in preamplifier and cable, while there were occurrences of single-event effect in mid-amplifier. The detector underwent 10% decrease of sensitivity to visible light. In addition, shielding cabinet was designed to provide good protection for electronics inside.
