Popis:	The radioluminescence spectral intensity of KU-1 and KS-4V fused quartz under neutron and gamma pulse irradiation was measured in the visible range (380–700 nm) in the pulse nuclear reactor BARS. Three groups of quartz samples were tested during the experiments, the first group – nonirradiated, the second and the third – preirradiated in the conventional nuclear reactor IR-8 up to neutron fluences of 6 × 10 19 n/cm 2 (total absorbed dose 2.8 GGy (Si)) and 6 × 10 18 n/cm 2 (total dose 0.3 GGy). The measurements were performed at temperatures of 18°C and 100°C. The intensity was quantified in terms of the photon emission, and the comparison was done with an estimated bremsstrahlung intensity for ITER plasma parameters. It is shown that KU-1 fused quartz is suitable for use as windows in the visible spectral range for ITER diagnostics.
