Meaurement of Cosmic Ray elemental composition from the CAKE balloon experiment
arXiv:0911.3500 · doi:10.1016/j.asr.2010.07.023
Abstract
CAKE (Cosmic Abundances below Knee Energies) was a prototype balloon experiment for the determination of the charge spectra and of abundances of the primary cosmic-rays (CR) with Z10. It was a passive instrument made of layers of CR39 and Lexan nuclear track detectors; it had a geometric acceptance of 0.7 msr for Fe nuclei. Here, the scanning and analysis strategies, the algorithms used for the off-line filtering and for the tracking in automated mode of the primary cosmic rays are presented, together with the resulting CR charge distribution and their abundances.
