Samples of three heavy crystalline materials: PbWO4, Bi4Si3O12, and PbF2 were irradiated in a high-intensity 24 GeV proton beam at the CERN PS to fluencies of 3.8×1013 protons/cm2. The optical transmission radiation damage was measured and all cryst

In this paper we describe the phenomenon of the stimulated recovery of radiation damage in lead tungstate scintillation crystals achieved via illumination by visible and infrared light. It allows fast and efficient in-situ recovery of the optical tra

A concept of a system to detect presence of fissile and radioactive materials in cargo and shipping containers is discussed. High energy gamma-radiography of an object may be used to retrieve information on mass and density distribution within it. Im

Irradiation damage of undoped and low Ce doped lutetium oxyorthosilicate has been investigated. Crystals were irradiated with both a 60 Co γ-quanta source with an absorbed dose of 2000 Gy and, at CERN PS, a high-rate 24 GeV proton beam with a fluenc
