Crystal calorimeter has traditionally played an important role in precision measurement of electrons and photons in high energy physics experiments. Recent interest in calorimeter technology extends its application to measurement of hadrons and jets with dual readout for both Cherenkov and scintillation light. Optical and scintillation properties of crystal scintillators commonly used in particle...
For multi-rectangle detection, this paper proposes a detection approach based on chain-code tracing. It improves the method of chain-code trace for getting rectangle contour based on geometric property of rectangle. Then divide this contour into four segments and determine rectangle by line fitting and ensure detect precision by affirm true rectangle using evidence collected. Numerical experiments...
Crystal calorimeter has traditionally played an important role in precision measurement of electrons and photons in high energy physics experiments. Recent interest in calorimeter technology extends its application to measurement of hadrons and jets with dual readout. Potential application of new generation scintillating crystals of high density and high light yield, such as LYSO, in high energy physics...
In this paper, we report an investigation on the radiation damage effects induced by neutrons in large size crystal scintillator: BGO, CeF3, LYSO:Ce and PWO. The irradiations were carried out by using fast neutrons from one 241Am-Be and two 252Cf sources. The optical and scintillation properties of these samples, including UV excitation and emission spectra, longitudinal transmission, light output,...
