The last decade has seen a renaissance in inorganic scintillator development for gamma ray detection. Lead tungstate (PbWO 4 ) has been developed for high energy physics experiments, and possesses exceptionally high density and radiation hardness, albeit with low luminous efficiency. Lutetium orthosilicate or LSO (Lu 2 SiO 5 :Ce) possesses a unique combination of high luminous efficiency, high density, and reasonably short decay time, and is now incorporated in commercial positron emission tomography (PET) cameras. There have been advances in understanding the fundamental mechanisms that limit energy resolution, and several recently discovered materials (such as LaBr 3 :Ce) possess energy resolution that approaches that of direct solid state detectors. Finally, there are indications that a neglected class of scintillator materials that exhibit near bandedge fluorescence could provide scintillators with sub-nanosecond decay times and high luminescent efficiency.

“…B ECAUSE of its high density (S.3 g/cm 3 ) and short radiation length (0.S 9 cm), PbW04 (PWO) crystals have been used to construct electromagnetic calorimeters (ECAL) for high energy physics (H EP) experiments, such as the CMS experiment at LH C [1]. It is also being considered for the future HEP experiments, where precision measurements of photons and electrons are important for their physics mission.…”

We report in this paper an investigation on radiation hardness of 20 cm long PWO-II crystals produced at BTCP for the proposed PANDA experiment at GSI. The optical and scintillation properties of PWO-II crystals, such as transmittance, light output and light response uniformity, were measured before and after y-ray irradiations at different dose rates. PWO-II crystals are compared to crystals used in the CMS experiment. Progresses are observed in the radiation hardness for PWO-II crystals. Its use for crystal calorimeters in future high energy physics experiments is discussed. To maintain crystal precision, a precision light monitoring system is mandatory to trace variations of crystal transparency in situ for a PWO crystal calorimeter in a radiation environment.

“…The PbWO 4 (PWO) single crystal became a subject of increasing interest in the recent years due to their practical usage as a scintillation detector in the compact muon solenoid (CMS) experiments and the large ion collider experiment (ALICE) at CERN [1][2][3]. The scintillation properties and radiation hardness were of particular importance.…”
