Ultrafast PWO scintillator for future high energy physics instrumentation

The development of lead tungstate scintillator with the scintillation decay decreased down to the subnanosecond domain is reported. The material exhibits a scintillation decay with a time constant of 640 ps at a light yield of 7 phe/MeV and a high radiation tolerance to the electromagnetic component...

Description
Summary:The development of lead tungstate scintillator with the scintillation decay decreased down to the subnanosecond domain is reported. The material exhibits a scintillation decay with a time constant of 640 ps at a light yield of 7 phe/MeV and a high radiation tolerance to the electromagnetic component of ionizing radiation. It is shown to be an outstanding candidate for dual readout of scintillation and Cherenkov photons in electromagnetic calorimetry at future collider experiments.
