SuperTIGER builds on the heritage of the smaller Trans-Iron Galactic Element Recorder (TIGER) flown from Williams Field in 2001 and 2003. This next-generation version is a large-area instrument that measures the elemental abundances of cosmic rays, from zinc to molybdenum. The instrument can detect an unprecedented combination of individual elements at an extraordinary resolution and statistical precision. The data collected will permit a sensitive test of the hypothesis that microquasars or other phenomena could superpose spectral features on the otherwise smooth energy spectra previously measured with less statistical accuracy.

Field Season Overview

Eight team members will be housed at McMurdo Station and will make day trips to the Long Duration Balloon (LDB) launch facility to prepare the SuperTIGER-2 balloon payload for a December launch. If the instrument launches and terminates this season, three team members will assist in recovery efforts.
