Galactic cosmic rays are relativistic nuclei measured directly by detectors flown above most, if not all, of the atmosphere, such as the Super Trans-Iron Galactic Element Recorder (SuperTIGER) and the CALorimetric Electron Telescope (CALET). SuperTIGER has successfully flown two times on stratospheric balloons over Antarctica in the 2012-2013 and 2019-2020 seasons at altitudes up to ~130,000 ft, which is above all but the last ~0.5% of the atmosphere. CALET has been flying on the International Space Station (ISS) in low-earth orbit since its launch on the HTV-5 rocket and installation on the ISS in August 2015 and is approved to continue operations through the end of 2024. This talk will touch on the broader science of these instruments but will primarily focus on measurements of ultra-heavy Galactic cosmic rays.
This colloquium will be live as well as on Zoom.
