The Trans-Iron Galactic Element.Recorder (TIGER) instrument was launched in December 2001 from McMurdo, Antarctica. TIGER is a cosmic-ray telescope that uses four scintillation counters, two Cherenkov detectors and a scintillating fiber hodoscope to determine the charge (Z) and energy of a particle. During the 31.8 day flight it measured ~100 ultra-heavy galactic cosmic-ray (GCR) events with Z > 30 and demonstrated charge resolution sufficient to resolve the individual elemental abundances in this region. The abundances of the Ultra-Heavy GCRs in this range can be used to distinguish between GCR source models. We present our measurements and discuss the implications for the GCR source.
