The CREAM calorimeter is comprised of 20 layers of 1 radiation length (X-0) tungsten interleaved with 20 layers of scintillating fibers with fifty 1 cm wide scintillating fiber ribbons per layer. The fiber light output is read out with multi pixel Hybrid Photo Diodes (HPDs) through various optical components. Measurements of the scintillation light generated in the fiber ribbons by radio-active sources, UV Light Emitting Diodes (LEDs), and particle beams confirm that they can meet the requirements of measuring cosmic-ray particle energies from similar to 10(12) to similar to 10(15) eV. The calorimeter design and results of various tests of its performance are presented.

Abstract
The CREAM calorimeter is comprised of 20 layers of 1 radiation length (X-0) tungsten interleaved with 20 layers of scintillating fibers with fifty 1 cm wide scintillating fiber ribbons per layer. The fiber light output is read out with multi pixel Hybrid Photo Diodes (HPDs) through various optical components. Measurements of the scintillation light generated in the fiber ribbons by radio-active sources, UV Light Emitting Diodes (LEDs), and particle beams confirm that they can meet the requirements of measuring cosmic-ray particle energies from similar to 10(12) to similar to 10(15) eV. The calorimeter design and results of various tests of its performance are presented.
