CREAM-I量热计的校准
Calibration of the CREAM-I calorimeter
摘要:
宇宙射线能量与质量(CREAM)量热计被设计用来测量能量范围从~10^11 eV到~10^15 eV的宇宙射线粒子的光谱。2004/2005年南极季节,该卫星作为CREAM-I号气球运载有效载荷的一部分在南极进行了首次飞行,其暴露时间达到创纪录的42天。将讨论使用各种束流测试数据的量热计校准,试图评估能量测量的不确定性。
英文摘要:
The Cosmic Ray Energetics And Mass (CREAM) calorimeter is designed to measure the spectra of cosmic-ray particles over the energy range from ~10^11 eV to ~10^15 eV. Its first flight as part of the CREAM-I balloon-borne payload in Antarctica during the 2004/05 season resulted in a recordbreaking 42 days of exposure. Calorimeter calibration using various beam test data will be discussed in an attempt to assess the uncertainties of the energy measurements.
