SuperTIGER instrument abundances of galactic cosmic rays for the charge interval 41 ⩽ Z ≤ 56
We report preliminary elemental abundance results from the 55-day long-duration-balloon flight of SuperTIGER (Super Trans-Iron Galactic Element Recorder) during the 2012-2013 austral summer. SuperTIGER measured the relative abundances of Galactic cosmic-ray (GCR) nuclei with high statistical precisi...

We report preliminary elemental abundance results from the 55-day long-duration-balloon flight of SuperTIGER (Super Trans-Iron Galactic Element Recorder) during the 2012-2013 austral summer. SuperTIGER measured the relative abundances of Galactic cosmic-ray (GCR) nuclei with high statistical precision and well resolved individual element peaks from â‚â‚€Ne to â‚„â‚€Zr. SuperTIGER also made exploratory measurements of the relative abundances up to ₅₆Ba. Although the statistics are low for elements heavier than â‚„â‚€Zr, we present, for the first time, relative abundance measurements of charges Z = 41-56 with individual element resolution.
