CALET Ultra Heavy Cosmic Ray Analysis Status*

The CALorimetric Electron Telescope (CALET) on the International Space Station (ISS) was launched August 19, 2015 and continues to return excellent data. CALET measures the fluxes of high-energy electrons, nuclei and gamma rays with its main calorimeter (CAL). The energy spectra of the more abundant cosmic-ray (CR) nuclei through $_{26}$Fe are measured with the CAL, which also has the dynamic range to measure the abundances of CR nuclei from $_{1}$H to $_{40}$Zr. CALET has a ultra-heavy cosmic-ray (UHCR) trigger that provides an expanded geometric acceptance such that in its approved 5 year mission on the ISS CALET will collect a UHCR data set with statistics comparable to that achieved with the first flight of the SuperTIGER balloon-borne instrument in a similar energy range. Analysis of the CALET UHCR data is ongoing, but preliminary results show reasonable agreement with SuperTIGER relative abundances of even charge UHCR nuclei. The CALET space-based measurements also complement the lower statistics and lower energy space-based UHCR measurements by ACE-CRIS.
