The calorimeter (CAL) was designed to measure the energy of the CR particles. The ISS-CREAM on-orbit data provide evidence that the CAL may have either suffered from an efficiency problem or its energy scale may be in need of calibration. As a result, a careful scrutiny of the absolute energy calibration of the CAL is required. We describe an approach to calibrate the energy scale using the on-orbit data of the boronated scintillator detector, which is independent of the CAL data and reduces potential bias. We discuss the issues revealed by the on-orbit data, demonstrate how this can be corrected using the boronated scintillator detector and present preliminary results.8 pagesen-USThis item is likely protected under Title 17 of the U.S. Copyright Law.
