Performance of the CREAM CREAM-V and CREAM CREAM-VI calor calorimeters in flight meters

摘要

The Cosmic Ray Energetics And Mass (CREAM) is a balloon balloon-borne experiment designed to study the composition and energy spectra of cosmic cosmic-ray parti particles. CREAM has flown six times from McMurdo Station in cles. Antarctica between December 2004 and December 2010. The payload for the CREAM CREAM-V flight employed a Timing Charge Detector (TCD), Cherenkov Camera (CherCam) and Silicon Charge Detector (SCD) for the cha charge rge measurement, and a Calorimeter (CAL) for the energy measurement. For the CREAM CREAM-VI flight, the payload only included the CherCam, SCD and CAL. The CAL was constructed of 20 layers tungsten plates interleaved with scintillating fiber ribbons, and used t to measure the elemental energy spectra of cosmic rays up to 10 o 15 eV. In this paper we present the performance of the CREAM CREAM-V (2009 2009-2010 season) and CREAM CREAM-VI (2010 2010-2011 season) calorimeters during flight, and show preliminary distributions of energy deposit deposited in the CAL.
