Welcome to SuperTIGER
Cosmic-Ray Balloon Experiment
Building on the success of TIGER (launched in 2001 and 2003), SuperTIGER (Super Trans-Iron Galactic Element Recorder) had a record-breaking 55-day flight over Antarctica in December 2012 – January 2013 and a 32-day flight in December 2019 – January 2020. This program is a collaboration among Washington University in St. Louis, Goddard Space Flight Center, California Institute of Technology, and Jet Propulsion Lab. With the data from these flights we are studying the origin of cosmic rays. Specifically, testing the emerging model of cosmic-ray origins in OB associations, as well as models for determining which particles will be accelerated. Recent detection events from LIGO-VIRGO have furthered a need to begin sampling the charge range where r-process production resulting from binary neutron star mergers (NSM)
