Detector systems based on inorganic heavy scintillator materials are limited in their performance due to severe radiation damage caused by hadrons. The present paper investigates a series of medium crystalline and glass ceramic samples using 150 MeV protons for irradiation studies. New materials, such as DSB:Ce show very promising features.
The application of crystalline materials in ionizing radiation detectors has played a crucial role the discovery properties matter. However, experiences gathered at high intensity machines such as LHC have indicated their limitations and underlined requirements for being more tolerable to damage particular caused by energetic hadrons. Systematic studies hardness inorganic optical scintillation propose both oxide fluoride crystals composed atoms with atomic numbers below 60. In this study we...
Meson photoproduction is a key tool for the experimental investigation of nucleon excitation spectrum. To disentangle specific couplings resonances, in addition to rather well measured pion and eta channels it mandatory obtain information on involving strange vector mesons higher mass pseudoscalar mesons, associated multi-particle final states with both charged neutral particles. In this respect, new BGO-OD experiment at ELSA accelerator University Bonn's Physikalisches Institut provides...
