Thick Crystal

Nowadays, single crystal scintillators play an key role in the scientific researches, high-energy physics and modern medical imaging. In this research, we studied the scintillation response of polished yttrium oxyorthosilicate with Ce-doped (Y2SiO5:Ce, YSO(Ce)) crystals grown by the Czochralski method. The nominal Ce3+ ion is about 0.5% for tested crystals. Energy resolution and photon yield of the scintillator are read out by the photomultiplier tube (XP5200B PMT) under excitation with gamma-rays. The polished YSO:Ce samples (5x5x1 mm3 and 5x5x3 mm3) was tested at room temperature. The 1 mm thick sample shows the better energy resolution than the 3 mm thick crystal. The light yield dependences on the height of crystal were evaluated under excitation with 662 keV gamma ray energy and the intrinsic light yield and loss parameter were also determined.

Right Ascension

A source of gamma rays has been found at right ascension 20h15m, declination +35°, with an uncertainty of 6° in each coordinate. Its flux is (1·5 ± 0·8) x 10-4photons cm-2sec-1at 100 MeV. Possible identifications are reviewed, but no conclusion is reached. The mechanism producing the radiation is also uncertain.

Low Altitude

AbstractThe experiment SONG (SOlar Neutron and Gamma rays) for the low altitude satellite CORONAS-I is described. The instrument is capable to provide gamma-ray line and continuum detection in the energy range 0.1 – 100 MeV as well as detection of neutrons with energies above 30 MeV. As a by-product, the electrons in the range 11 – 108 MeV will be measured too. The pulse shape discrimination technique (PSD) is used.
