“…C ERIUM-doped Gd 3 Al 2 Ga 3 O 12 (Ce:GAGG) is a relatively new single crystal scintillator with several properties that make it interesting for applications such as gamma spectroscopy [1], [2], alpha particle detection [3], [4] and nuclear medicine [5]- [9]. The material was first reported in 2011 and single crystals can be grown by the Czochralski (Cz) method [10], [11].…”

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.

“…Preliminary studies of energy resolution and timing performance of GAGG crystals readout by a variety of photon detection technologies (PMT, MPPC, PIN diode) show that the crystal has promise in medical imaging and gamma spectroscopy applications [8], [9]. Figure 1 shows a photograph of the 3mm×3mm×30mm GAGG scintillator crystals together with a packaged 3mm×3mm active area SiPM detector.…”

“…Figure 4 compares the typical spectral sensitivity of the Non-P (M series) and P-on-N (B series) SiPM devices together with the emission spectrum of the GAGG scintillator. The emission spectrum of GAGG is taken from [9]. While the Pon-N device has a higher overall peak efficiency, the overlap of the spectral response of the N-on-P device with the emission spectrum of GAGG promises a higher detection efficiency and hence an improved energy resolution.…”

Abstract-Silicon Photomultiplier (SiPM) detectors are investigated world-wide as a suitable replacement for the conventional vacuum based PhotoMultiplier Tube (PMT) and are enabling applications otherwise not possible with PMT detectors. Progress in recent years has been substantial with SiPM detectors pushing the boundaries in energy and time resolution as well as photon detection efficiency and active surface area. In this paper we report on the performance of a gamma detector comprising latest generation SiPM detectors from SensL coupled to novel Cerium doped Gd3Al2Ga3O12 (GAGG) scintillators from Furukawa, Japan. Both 3mm×3mm N-on-P and P-on-N SiPM detectors have been optically coupled to 3mm×3mm×30mm crystals. An energy resolution (662 keV Cs-137) of 9.4% has been measured for GAGG crystal coupled to a 3mm×3mm N-on-P SiPM detector.
