A balloon-borne experiment using a superconducting solenoidal magnet spectrometer is being carried out with aims at making a precise measurement of low energy antiproton flux in cosmic rays and a highly sensitive search for primordial antimatter in the Universe. The spectrometer has a unique cylindrical configuration associated with a thin superconducting solenoidal magnet and is realizing a geometrical acceptance of 0.5 m2sr. The first scientific ballooning flight was successfully carried out in northern Canada, in summer, 1993, and the second flight is being prepared to be carried out in summer, 1994. Performance of the spectrometer in the first flight and progress of the experiment are described.
