Performance of the CREAM calorimeter module during its first flight of 42 days

Year: 2005
Type: article
Abstract: The Cosmic Ray Energetics And Mass (CREAM) calorimeter module consists of a tungsten/scintillating-fiber sampling calorimeter preceded by two graphite targets with scintillating fiber hodoscopes, and a pixelated Silicon Charge Detector (SCD). The calorimeter is designed to measure incident particle energies, and the hodoscopes are designed to provide incident particle tracking information. The calorimeter and hodoscopes both use Hybrid Photo Diodes (HPDs) with high voltage settings at 6 kV for the calorimeter and 9 kV for the hodoscopes. We describe the performance of the calorimeter module during a 42 day flight at balloon altitude (2 - 6 mbars), including HV stability, noise values as calculated from pedestal value distributions, gain variations of the electronics, and trigger. In addition, the calorimeter calibration will be discussed.
