Sp. Tretyakova et al., EFFECT OF HIGH ALPHA-PARTICLE FLUENCES ON PHOSPHATE-GLASS DETECTORS, Instruments and experimental techniques, 41(4), 1998, pp. 493-495
The effect of high alpha-particle fluences (3 x 10(13)-2 x 10(15) cm(-
2)) on the line-recording properties of the two types of phosphate-gla
ss detectors with different compositions was studied. The glass sample
s were exposed to accelerated Si ions and fission fragments before and
after their irradiation with the accelerated 3.1-MeV alpha-particle b
eam, perpendicular to the sample surfaces, and with alpha-particles fr
om a Ra-226 radioactive source in a solid angle of about 2 pi. It was
shown that the recording properties of glass detectors depended on the
alpha-particle fluence, spatial distribution of the alpha-particle pa
ths, and glass type. The critical alpha-particle fluences, above which
the detector properties changed, were determined.
