A. Gorshkov et al., Measurements of the radiation resistant fused quartz radioluminescence spectral intensity under irradiation in the pulse nuclear reactor, J NUCL MAT, 273(3), 1999, pp. 271-276
The radioluminescence spectral intensity of KU-1 and KS-4V fused quartz und
er neutron and gamma pulse irradiation was measured in the visible range (3
80-700 nm) in the pulse nuclear reactor BARS. Three groups of quartz sample
s 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 x 10(19) n/cm(2) (total absorbed dose 2.8 GG
y (Si)) and 6 x 10(18) n/cm(2) (total dose 0.3 GGy), The measurements were
performed at temperatures of 18 degrees C and 100 degrees 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 visib
le spectral range for ITER diagnostics. (C) 1999 Elsevier Science B.V. All
