Description

Scintillation Crystals and Detectors: PWO

Lead tungstate (PbWO4) is a scintillation crystal that is commonly used in detectors for high-energy physics experiments, medical imaging, and radiation detection.

PbWO4 (PWO) is a scintillation crystal commonly used in high-energy physics experiments and medical imaging applications. It has a high density and high atomic number, which makes it an excellent choice for detecting high-energy photons, such as those produced in positron emission tomography (PET) and gamma ray spectroscopy. PWO has a short decay time and high light yield, which means that it can produce fast and efficient signal readout. Additionally, PWO is relatively radiation hard, meaning that it can withstand high levels of radiation without significant degradation in performance.
