Polar balloon flights with a scaled version of CALET

The CALorimetric Electron Telescope (CALET) is a candidate instrument to be installed on the JEM-EF facility on the International Space Station (ISS). It is optimized for the search of nearby sources of acceleration of cosmic ray electrons in the TeV energy range. In addition, the combination of a large collection power and long observation time allows for precision studies of the elemental composition of VHE nuclei and of their spectral features. Earlier versions of the instrument have been flown on balloons in Japan and Antarctica; a 1/64 scaled version (bCALET-1) was launched from Sanriku in 2006 and a 4 times larger payload is in preparation. In this paper, a 1/4 version of CALET is proposed as a candidate balloon payload for Arctic flights.
