Description
Europium doped Strontium Iodide (SrI2(Eu)) is a promising scintillation detector for use in radiation detection because of its high light output (80000 -110000 photons per MeV), excellent energy resolution around 3 % and low background radiation. These good characteristics make it promising for the gamma-ray imaging in the environmental applications as an alternative of Sodium Iodide (NaI(Tl)). For fabricating a compact radiation detectors, the coupling to solid-state photosensors, such as SiPM, is necessary, which has typically a square shape. The rectangular SrI2 scintillators (25.4 x 25.4 x 10 mm) are fabricated with “Liquinert” process for removal of water, and evaluated with Photomultiplier and TSV-type MPPC. The initial results shows the excellent energy resolution around 3.6 % at 662 keV with PMT. The detail results coupled to TSV-MPPC with different temperature and shaping time will be shown in the conference.
