“…In contrast with this systematic behavior, the variations in LSO light output are insignificant and the energy resolution is fairly insensitive to crystal position with the Lumirror E60L Polyester Film and the 3M V2000 Radiant Light Film. Whereas the unpolished surfaces of the crystals may have some effect, the latter is not inconsistent with the fact that some other factors independent of light collection are involved in the signal variance of this scintillator [7][8][9]. The relative light yield of GSO is the lowest with all three separators (by ~10% on the average relative to BGO and LSO), while the relative light yield achieved with BGO is the best overall when compared to the single crystal wrapped in Teflon.…”

Thin, highly reflective, opaque separators are required to assemble compact arrays of small discrete scintillation crystals used in conjunction with photodiode array readouts in high-resolution imaging applications. Mechanical stability, individual detector performance, and ease of handling for wrapping crystals are the main factors to be considered in the choice of a suitable separator. Three different types of reflective materials were tested with 4 4 arrays of LSO, BGO and GSO: Tyvek 1058D paper, Toray Lumirror E60L Polyester Film, and 3M VM2000 Radiant Light Film. The light output and intrinsic energy resolution of individual crystals were measured as a function of their position in the arrays and the results were compared to simulation of light collection efficiency obtained with DETECT97. Optical crosstalk between adjacent and diagonal pixels was evaluated. Lumirror film consistently yielded superior results with BGO. With LSO and GSO, the 3M reflector was found to provide slightly better light output and energy resolution. Despite the sharp cutoff in spectral reflectivity at 400 nm with this reflector, the crosstalk between adjacent LSO crystals was not found to be significant. 879 0-7803-7324-3/02/$17.00 © 2002 IEEE

“…Furthermore, the normalization reduces the uncertainty in the process of photon generation. The energy resolution of a scintillator R S can be split into one term resulting from the statistical variance R E and the intrinsic crystal resolution R I , 25,26…”

“…Cerium-doped lutetium oxyorthosilicate (LSO) has attracted a considerable attention due to its many important advantages, such as excellent light yield, high density, short decay time, suitable emission wavelength, and very good chemical stability compared to other scintillators [1][2][3][4][5] as a promising scintillator orphosphor for applications in positron emission tomography, nuclear physics, high-energy physics and environmental monitoring [5][6][7][8]. So, the study of the growth and scintillation properties of LSO crystal has become an attractive and interesting field in the past decade.…”
