Project Description:
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 is capable of detecting 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:
Super-TIGER will be launched on a stratospheric balloon from Williams Field as a part of the CSBF ballooning operations (Stepp A-145). The field party of ten will begin arriving at McMurdo in late October with the expectation that the instrument will be launched in early to mid-December. Soon after launch, most of the team will return home while two or three will stay to monitor data and participate in recovery operations. Several members of the science team may camp at the recovery site for a few days to disassemble and pack the instrument for transport back to McMurdo and ultimately to the home institution.
