The absolute light outputs of BGO, CsI(Tl) and some new Ce-doped crystals have been measured to an accuracy about /spl plusmn/5% using calibrated XP2020Q photomultipliers standard S3590.03 S2740.03 photodiodes. use small crystals, 9 mm in diameter 1 thick, reduces the corrections for imperfections collection process photoelectron by photomultipliers. light-output 8500/spl plusmn/350 ph/MeV (photons/MeV) BGO agree well with earlier measurement done Holl et al. (1988). carried out study...
The scintillation properties of LuAG:Ce and YAG:Ce crystals were compared with LYSO:Ce crystal under ¿ -ray excitation. Light yield non-proportionality energy resolution measured a Photonis XP5500B PMT. resolution, obtained in this work for 662 keV -rays, was 6.7, 7.0 8.7%, respectively, LuAG:Ce, detectors. values reflect the influence light on resolution. A fast component decay is faster than that crystal, whereas relative intensity higher crystal. coincidence time 511 annihilation quanta,...
We have studied the nonproportionality and intrinsic energy resolution of cerium doped YSO, GSO, LSO LGSO crystals. While YSO similar light output, GSO ca. 70% 20% lower output than LSO, respectively. a compound containing fairly elements, was expected to proportional vs. energy, like YAP:Ce. Surprisingly it has almost same non-proportional as GSO. The is followed by large values resolution. comparison YSO-LSO YAP-LuAP pairs indicates that high proportionality connected with structure...
Scintillation detectors consisting of LSO, LuAP and YAP crystals fitted to bevelled-edge large area avalanche photodiodes 10 mm in diameter characterised by a high quantum efficiency up 68% at 350 nm wavelength were studied. Among the properties measured number electron-hole pairs, energy resolution noise contribution LAAPDs shaping time constants down 20 ns different gains. High pair numbers 11000/spl plusmn/550 e-h/MeV 19500/spl plusmn/980 for LSO measured, respectively. The /sup 137/Cs...

The energy resolution of small NaI(Tl), CsI(Tl), BGO, GSO, YAP and LSO crystals has been studied using 16 mm diameter large area avalanche photodiodes (LAAPD) a 52 photomultiplier. best result 4.8% for 662 keV /spl gamma/-rays from /sup 137/Cs source was obtained with 9 in by high CsI(Tl) scintillator coupled to an LAAPD. Measuring the number primary electron-hole pairs produced LAAPD photoelectrons photomultiplier, as well noise contribution LAAPD, allowed quantitative discussion results....
