David Mahon (University of Glasgow)13/02/2013, 09:00TalkCosmic-ray muons are highly penetrative charged particles observed at sea level at a rate of 1 per square cm per min. They interact with matter primarily through Coulomb scattering. These properties are exploited in muon tomography to image objects inside industrial nuclear waste containers. A prototype scintillating-fibre detector has been developed at the University of Glasgow in...Go to contribution page

Jun Kataoka (Waseda University)13/02/2013, 09:25TalkOne year after Japan’s nuclear disaster, the invisible threat of radiation lingers around homes and businesses near the Fukushima Daiichi Nuclear Plant. Various gamma cameras are being developed and are now undergoing careful field tests. Although some are compact, the detector weight still exceeds 10 kg due to the thick mechanical collimator. Other models use electronic collimation but have...Go to contribution page

Arno Richard Knapitsch (CERN)13/02/2013, 09:50TalkOne of the problems in heavy scintillating materials is related to their high index of refraction. As a consequence, a large part of the scintillation light produced in the bulk material is trapped inside the crystal due to total internal reflection. Recent developments in the area of nanophotonics were showing now that those limitations can be overcome by introducing a photonic crystal slab...Go to contribution page

Mr Akira Suzuki (Institute for Materials Research)13/02/2013, 10:15TalkRecently, we have developed a novel oxide scintillator (La,Gd)_2Si_2O_7 (La-GPS) crystal doped with 1-mol\% Ce grown by floating zone method. This crystal had excellent scintillation properties measured with a photomultiplier (PMT, Hamamatsu R7600U): a high light output of approximately 36,000 photons/MeV, good energy resolution (FWHM) of 5.0\% at 662 keV and fast decay time of 46 ns....Go to contribution page

Prof. Yoshiyuki Fukuda (Faculyu of Education, Miyagi University of Education)13/02/2013, 11:30TalkAn organic liquid scintillator containing zirconium complex was studied for neutrinosless double beta decay. We have synthesized tetrakis(8-quinolinolate) zirconium as a complex and found their good solubility (2 w.t.%) in Benzonitrile, which has good light yield of primary scintillation for gamma-rays. The photo-luminescence was measured, and the maximum peak was found around 548nm. We made...Go to contribution page

Dr Xilei Sun (IHEP)13/02/2013, 11:55TalkThe dual light-emitting crystals can reflect the different ranges of nuclear recoils and electron recoils by the ratio of the two different scintillation components. CsI(Na) crystals at temperatures of ~-100 ℃ have the best performance in several candidate crystals. An experiment called CINDMS is proposed for WIMPs direct searches based on the CsI(Na) crystals detector by IHEP. The 1T-scale...Go to contribution page

Dr Luca Pattavina (I.N.F.N. Milano-Bicocca)13/02/2013, 12:20TalkThe first idea of using a scintillating bolometer was suggested for solar neutrino experiments in 1989. After many years of developments, now we are able to exploit this experimental technique, based on the calorimetric approach with cryogenic particle detectors, to investigate rare events such as Neutrinoless Double Beta Decay and interaction of Dark Matter candidates. The possibility to...Go to contribution page
