Fig. 3From: Coincidence energy spectra due to the intrinsic radioactivity of LYSO scintillation crystalsTwo detector modules, each consisting of a monolithic LYSO scintillation crystal, wrapped in white Teflon and brown tape. The crystals are coupled to SiPM arrays, SensL ArrayC-60035-64P, and mounted on aluminum cases, which in turn sit on a pair of optical rails to vary the detector separation distanceBack to article page
