In 1976, 1977 and 1978, three balloon flights were conducted to measure the energy spectra of cosmic ray nuclei. A gas Cerenkov detector with different gas thresholds of 8.97, 13.12, and 17.94 GeV/nuc was employed to extend these measurements to high energies. The total collection factor for these flights is greater than twenty m('2) ster-hr. Individual charge resolution is achieved over the charge range Z = 4 - 26, and overlapping differential spectra are obtained from the three flights up to (TURN)100GeV/nuc.
