Elemental spectra from the first ATIC flight
The Advanced Thin Ionization Calorimeter (ATIC) instrument is a balloon-borne experiment designed to measure the composition and energy spectra of Z = 1 to 26 cosmic rays over the energy range from ̃ 1011 to 10 eV. The instrument consists of a silicon matrix charge detector, plastic scintillator strip hodoscopes interleaved with graphite interaction targets, and a fully active Bismuth Germanate (BGO) calorimeter. ATIC had two successful Long Duration Balloon flights launched from McMurdo Station, Antarctica in 2000 and 2002. In this paper, preliminary energy spectra of C and O measured during the first 16-day flight are presented.
