Abstract

PoGOLino is a balloon-borne scintillator-based experiment developed to study the largely unexplored high altitude neutron environment at high geomagnetic latitudes. The instrument comprises two detectors that make use of LiCAF, a novel neutron sensitive scintillator, sandwiched by BGO crystals for background reduction. The experiment was launched on March 20th 2013 from the Esrange Space Centre, Northern Sweden (geomagnetic latitude of $65^\circ$), for a three hour flight during which the instrument took data up to an altitude of 30.9 km. The detector design and ground calibration results are presented together with the measurement results from the balloon flight., Comment: Accepted for publication in Nuclear Inst. and Methods in Physics Research, A

Abstract

Al(DMSO)6SbCl6 and Ga(DMSO)6SbCl6 single crystals were synthesized by the solvent evaporation method and their optical and scintillation properties were investigated. Broad photoluminescence (PL) and scintillation peaks derived from the recombination of the self-trapped excitons were confirmed at 500–550 nm. The calculated PL quantum yields of Al(DMSO)6SbCl6 and Ga(DMSO)6SbCl6 were, respectively, 99.0 and 92.2%. The PL and scintillation decay time constants were estimated to be approximately 2.0 µs. The afterglow levels at 20 ms after X-ray irradiation for 2 ms were obtained to be 98 ppm (Al(DMSO)6SbCl6) and 63 ppm (Ga(DMSO)6SbCl6). The light yields (LY) of Al(DMSO)6SbCl6 and Ga(DMSO)6SbCl6 were 1100 and 800 photons/MeV under 137Cs γ-rays (662 keV) exposure. [ABSTRACT FROM AUTHOR]
