The Cosmic Ray Energetics and Mass (CREAM) timing charge detector
/ Ahn, H S ; Allison, P S ; Bagliesi, M G ; Beatty, J J ; Bigongiari, G ; Boyle, P ; Childers, J T ; Conklin, N B ; Coutu, S ; DuVernois, M A et al.
The use of detectors based on plastic scintillator with photomultiplier tubes (PMTs) is common in cosmic-ray experiments to differentiate particle charges. However, in the presence of a calorimeter, the standard method of pulse charge integration over a time longer than a PMT pulse is hampered by abundant albedo particles. [...]

After successful recovery of the first CREAM (Cosmic Ray Energetics And Mass) instrument during the 2004\/5 Antarctic campaign, the calorimeter was refurbished for the third launch, planned for December 2007. In this CREAM-III calorimeter, the optics were replaced with multi-clad fiber ribbons to enhance the light signal. [...]

CREAM for high energy composition measurements
/ Seo, E S ; Ahn, H S ; Allison, P S ; Beatty, J J ; Choi, M J ; Conklin, N B ; Coutu, S ; DuVernois, M A ; Ganel, O ; Kim, K C et al.
Ground-based indirect measurements have shown that the cosmic-ray allparticle spectrum extends many orders of magnitude beyond the energy thought possible for supernova acceleration. Our balloon-borne Cosmic Ray Energetics And Mass (CREAM) experiment is capable of extending direct measurements of cosmic-rays to the supernova energy scale of 1015 eV in a series of Ultra Long Duration Balloon (ULDB) flights.

The Cosmic Ray Energetics And Mass (CREAM) is a balloon-borne experiment designed to measure the composition and energy spectra of cosmic rays of charge Z = 1 to 26 up to an energy of ~ 10^15 eV. CREAM had two successful flights on long-duration balloons (LDB) launched from Mc- Murdo Station, Antarctica, in December 2004 and December 2005. [...]

The CREAM calorimeter, designed to measure the spectra of cosmic-ray nuclei from under 1 TeV to 1000 TeV, is a 20 radiation length (X0) deep sampling calorimeter. The calorimeter is comprised of 20 layers of tungsten interleaved with 20 layers of scintillating fiber ribbons, and is preceded by a pair of graphite interaction targets providing about 0.42 proton interaction lengths (\lambda int).
