Abstract
The Cosmic Ray Energetics And Mass (CREAM) instrument includes 6 orthogonal layers of scintillating fibers in three hodoscopes (S0, S1 and S2) for supplementary charge identification and particle tracking information. An additional single layer detector (S3) is included for triggering purposes. Hodoscopes S0 and S1 are located directly above the upper of two carbon interaction targets, and S2 is positioned. between the two targets. S3 is located between the lower target and the calorimeter. Since each fiber has slightly different properties, light yields and attenuation curves of fibers in S0, S1, and S3 were studied individually. These fiber characteristics and results of beam tests performed at CERN in Nov 2003 are presented. Simulation results for energy deposits in S3 are also discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
