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. [...]

The CREAM-III Calorimeter
/ Malinin, A (Maryland U.) ; Lee, M H (Maryland U.) ; Ahn, H S (Maryland U.) ; Ganel, O (Maryland U.) ; Han, J H (Maryland U.) ; Jeon, J A (Ewha Women's U., Seoul) ; Kim, C H (Maryland U.) ; Kim, K C (Maryland U.) ; Lutz, L (Maryland U.) ; Nam, S (Ewha Women's U., Seoul) et al.
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. [...]

Elemental Spectra from the CREAM-I Flight
/ Ahn, Hoseok ; Allison, P S ; Bagliesi, M G ; Beatty, J J ; Bigongiari, G ; Boyle, P J ; Childers, J T ; Conklin, N B ; Coutu, S ; Duvernois, M A et al.
The Cosmic Ray Energetics And Mass (CREAM) instrument 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 ∼1015 eV. CREAM had two successful flights on long-duration balloons (LDB) launched from McMurdo Station, Antarctica, in December 2004 and December 2005. [...]

Measurements of High-Energy Heavy Nuclei with the CREAM-I TRD
/ Wakely, Scott P (Chicago U.) ; Ahn, H S (Maryland U.) ; Allison, P S (Ohio State U.) ; Bagliesi, M G (U. Siena (main) ; INFN, Siena) ; Beatty, J J (Ohio State U.) ; Bigongiari, G (U. Siena (main) ; INFN, Siena) ; Boyle, P J (Chicago U., EFI) ; Brandt, T J (Ohio State U.) ; Childers, J T (Minnesota U.) ; Conklin, N B (Penn State U.) et al.
The balloon-borne cosmic-ray experiment CREAM-I (Cosmic-Ray Energetics And Mass) completed a successful 42-day flight during the 2004-2005 NASA\/NSF\/NSBF Antarctic expedition. CREAM-I combines an imaging calorimeter with charge detectors and a precision transition radiation detector (TRD). [...]

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.

Development of RE1/1 RPCs for the CMS muon trigger system
/ Park, S (Korea U., KODEL) ; Ahn, S H (Korea U., KODEL) ; Akimenko, S (Serpukhov, IHEP) ; Anan, P S (CERN) ; Bahk, S Y (Wonkwang U.) ; Ban, Y (Peking U.) ; Cai, J (Peking U.) ; Cho, S W (Korea U., KODEL) ; Crotty, I (CERN) ; Ge, Y C (Peking U.) et al.
The first six Resistive Plate Chambers (RPCs) of RE1/1 in the forward region of the Compact Muon Solenoid (CMS) detector were constructed and are being tested. These RPCs cover the pseudo-rapidity region from 1.6 to 2.1 and will serve as the base detector for the CMS RPC muon trigger. [...]
