The CREAM-III Calorimeter

After successful recovery of the first CREAM (Cosmic Ray Energetics And Mass) instrument during the 2004/5 Antarctic campaign, the calorimeter was refurbished for a third flight, planned for December 2007. In this CREAM-III calorimeter, the optics were replaced with multi-clad fiber ribbons to enhance the light signal, and new readout electronics boards reduce noise even further than the previous low-noise version. These improvements allow increased sensitivity to low energy showers. A new assembly structure has also been fabricated for ease of recovery. This refurbished calorimeter was calibrated at a CERN test beam in October 2006, and is now being integrated with the rest of the CREAM detector suite. The construction of the calorimeter and tests of its optical and electronic components will be discussed.
