“…This led to the reporting of unrealistic negative concentrations on a few occasions, though a concentration of zero fell within the margin of error for most of these negative measurements. These could possibly be attributed to a marginally elevated count rate during background measurement, perhaps from washout of radon daughters or other nuclides, but is more likely caused by statistical fluctuation and thermal effects within the NaI(Tl) detector (Moszy nski et al, 2006).…”

“…These measurements are triggered by our earlier studies, which we performed with several scintillation crystals coupled to photomultipliers (PMT) at a wide range of temperatures and various peaking times [1] as well as by the results of Ianakiev et al [2]. The data showed a variation of both light output and energy resolution with temperature, which makes it important to explore not only for scientific but also the practical reason for Manuscript this effect.…”

The performance of a NaI(Tl) crystal coupled to a Large Area Avalanche Photodiode (LAAPD) was investigated as a function of temperature in the range from -40ºC to +23ºC. The number of electron-hole pairs created per 1 MeV of γ-ray energy detected by the scintillator, non-proportionality and the energy resolution for various peaking times were measured. It showed a significant variation of the the light output and the energy resolution of a NaI(Tl) crystal at reduced temperatures down to -40°°°°C, as measured with different peaking times in the spectroscopy amplifiers. A large slowing down of the light pulse, caused by the intense slow component of the light pulse, requires long peaking times (up to 48 μ μ μ μs) in order to optimize the energy resolution at the most reduced temperatures. In these conditions of a full integration of the light, a weak variation of the light output of a NaI(Tl) crystal is observed, corresponding to -0.16%/°C. The non-proportionality characteristics and intrinsic resolution are somewhat distorted by a partial integration of the light by too short shaping in the amplifier. It confirms the earlier observations that, for crystals which exhibited two component decays of the light pulse, the best non-proportionality and the lowest intrinsic resolution are achieved for the full integration of the light.Index Terms-NaI(Tl), non-proportionality of light output, temperature dependence, intrinsic energy resolution, large area avalanche photodiode.

“…The measurements were done in the optimal conditions for each detector, using constant fraction timing (CFD) for LaBr 3 , low level leading-edge for NaI(Tl) and CFD timing with partly integrated light pulse for BGO, following [15] and [16]. In the case of measurements with Pu-Be source, the threshold was at 1 MeV.…”

The quest for finding the suitable detector for application in neutron activation analysis triggered us to investigate the properties of three 3"× 3" cylindrical scintillation detectors. The emphasis was put on the detectors' properties in the multi-MeV energy region as well as their response to neutron radiation. In this work we compare energy resolution efficiency and timing properties of BGO, LaBr 3 and NaI(Tl) scintillation detectors coupled to Photonis spectrometric photomultiplier tubes.
