“…The intensity of the luminescence in the 450e600 nm range decreases as the concentration of Lu increases, as was previously shown in the work of Sidletskiy et al, 2010). The intensity of the afterglow affects the crystal's energy resolution (Moszynski, 2010). Table 1 shows the values of the spectral matching factors of the (Lu,Gd) 2 SiO 5 :Ce with optical detectors, such as with various types of photocathodes used in photomultipliers, with position sensitive and silicon photomultipliers (SiPMs), used in indirect nuclear medical imaging detectors.…”

“…Scintillators in crystal form are widely applied in nuclear medicine, for example in positron emission tomography (PET) scanners (Ermis et al, 2014;Sreebunpeng et al, 2014). Among the various crystal detectors, cerium (Ce 3þ ) doped scintillators are the dominant due to their internal properties, such as, fast and high emission efficiency and energy resolution (Sidletskiy et al, 2009(Sidletskiy et al, , 2010Moszynski, 2010;Sidletskiy et al, 2010;Sidletskiy et al, 2014;Sreebunpeng et al, 2014). Gadolinium silicate Gd 2 SiO 5 (GSO) and lutetium silicate Lu 2 SiO 5 (LSO) crystals have been widely used in PET scanners (Sidletskiy et al, 2009(Sidletskiy et al, , 2010.…”

“…where δ sc is the intrinsic energy resolution of the crystal, δ p is the transfer resolution, δ st is the statistical contribution, defined by the number of detected photons and the detector noise, and ∆E/E is the energy resolution of the scintillationsensor system [19]. The main contribution to the intrinsic resolution of the crystal is the non-proportionality in the number of scintillation photons generated as a function of gamma energy.…”

Abstract-Scintillators are a critical component of sensor systems for the detection of ionizing radiation. Such systems have a diverse portfolio of applications from medical imaging, well logging in oil exploration and detection systems for the prevention of the illicit movement of nuclear materials. The rare earth element cerium is an ideal dopant for a variety of host scintillating materials due to the fast 5d1 → 4f radiative transition of Ce 3+ . Cerium-doped Gadolinium Aluminium Gallium Garnet (Ce:GAGG) is a relatively new single crystal scintillator with several interesting properties. These include high light yield; an emission peak well-matched to silicon sensors; and a low intrinsic energy resolution. Moreover, the material has a high density and is non-hygroscopic. In this article we review the properties of cerium-doped GAGG and report Energy Resolution (ER) measurements over the temperature range -10• C to +50• C for 3 × 3 × 30 mm 3 Ce:GAGG crystals optically coupled to a Silicon Photomultipler (SiPM) sensor with a 3mm × 3mm active area. In addition the linearity of the scintillator-SiPM response as a function of gamma energy is reported.

In this research, scintillation properties of Cs 2 LiYCl 6 :Ce (CLYC) scintillation material were studied by Compton scattering technique and the samples were irradiated with eight different photon energies using these technique. Photon interactions have been calculated by WinXCom program at 216-662 keV. The mass attenuation coefficient m )and partial interactions, light yield and non-proportionality were presented. The values of increased toward the decrease of gamma ray energies and are influenced by photon energy and chemical compositions. The partial interactions found that three energy relative to the partial processes first photoelectric absorption, second incoherent (Compton) scattering and third coherent (Rayleigh) scattering.Moreover, the crystal were higher at the low photon energy and decreased with increasing the photon energy. The results of scintillation properties show that slightly increased when increasing the photon energy.The non-proportionality shows demonstrated excellent proportional property in the energy range, the non-proportionality is about 1.5%.
