The CAKE experiment: Progress and new results

CAKE (cosmic abundances below the knee energies) is a prototype balloon experiment for the determination of the charge spectra of the primary cosmic-ray nuclei with Z>28 and the search for exotic heavy particles in the primary cosmic radiation. CAKE is made of stacks of CR39® and Lexan® nuclear track detectors; it has a geometric acceptance of about 1.7 m2 sr for Fe nuclei. Here, the scanning strategy and the algorithms used for tracking in automatic mode of the CR events are presented.
