Super-TIGER is a new, large-area instrument for measurement of the abundances of elements of atomic number Z in the interval 30≤Z≤42; with an unprecedented combination of individual-element resolution and statistical precision and will make exploratory measurements through Z=56. It will test and clarify the emerging model of cosmic-ray origin in OB associations, as well as models for atomic processes by which nuclei are selected for acceleration. It will also measure with high statistical accuracy the energy spectra of the more abundant elements of 14≤Z≤28; at energies 0.8≤E≤10; GeV/nucleon. These spectra 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. Super-TIGER builds on the heritage of the smaller Trans-Iron Galactic Element Recorder (TIGER), successfully flown on two balloons launched in Antarctica in December of 2001 and 2003, yielding a total of 50 days of data and producing the first well-resolved measurements of elemental abundances of the elements 31Ga, 32Ge, and 34Se. Super-TIGER is a forerunner of a similar instrument, the Energetic Trans-Iron Composition Experiment (ENTICE), currently being studied as part of the Orbiting Astrophysical Spectrometer in Space (OASIS), one of the NASA Astrophysics Strategic Mission Concept Studies. ENTICE would have sufficient exposure and resolution to measure even the rarest individual elements including the actinides, 90Th, 92U, 94Pu, and 96Cm.
