Stolzite. Lead tungstate crystals have the optical transparency of glass combined with much higher density (8. 28 gcm 3 vs 2. 2 gcm 3 for fused silica). They are used as scintillators in particle physics because of their short radiation length (0. 89 cm), low Molire radius (2. 2 cm), quick scintillation response, and radiation hardness.Lead tungstate (PbWOsub 4) is a new scintillating material which is of great interest for use in high energy electromagnetic calorimeters. It has a very high density, short radiation length and small Moliere radius and has a scintillation light output which peaks between nm with a decay time in the range from 515 ns. lead tungstate radiation length

Lead tungstate (PbWOsub 4) is a new scintillating material which is of great interest for use in high energy electromagnetic calorimeters. It has a very high density, short radiation length and small Moliere radius and has a scintillation light output which peaks between nm with a decay time in the range from 515 ns.

Lead tungstate was chosen by the CMS experiment [ 1 because of its high den sity, low cost and fast decay time. Lead hmgstate (PbW04) crystals are a new type of heavy scintillator which have a high density of 8. 3 gcme3, a short radiation length of 0. 89 cm and a small Molibre radius of 2. 2 cm. Lead tungstate has high density, short radiation length, fast scintillation decay time and stronger radiation damage resistance, is a natural radiation protection king, compared with pure tungsten, lead tungstate has higher mechanical properties and can adapt to difficult radiation operation.lead tungstate radiation length Lead tungstate crystalline material is transparent in the visible spectrum, colourless, birefringent and nonhygroscopic. It has density 8. 28 gcm 3, index of refraction at 600 nm n0 ne, photoelastic constant 0. 13 MPa 1, residual stress constant 1. 67 MPa, melting point 1123C.

Lead Tungstate (PbWO4) crystal is a scintillator which has been used as the detect material by several high energy physics devices, e. g. , CMS detector in CERN. The crystal is distinguished by its fast decay time, high density and strong radiation hardness. lead tungstate radiation length Atomic and Nuclear Properties of Materials for more than 300 materials This page is upgraded as needed in response to suggestions and requests for new materials. Performance Considerations Light yield Speed (scintillation decay time) Radiation length Molire radius Resistance to radiationinduced darkening Emission spectrum Cost (including implications for associated detectors) The relative weight given to these considerations depends on the application. How can the answer be improved?
