The experimental goal of the CAPRICE experiment was to measure antiprotons, positrons and light isotopes up to ca. 6 GV. The magnet spectrometer was not changed from the IMAX and TS93 flights. For particle identification a Calorimeter and a RICH-counter were used:
  • The imaging silicon-tungsten calorimeter used in the TS93 flight was improved (additional layers were added).
  • A new NaF-RICH counter built by the Stockholm group was installed.
    The instrument was launched on august 8, 1994 from Lynn Lake, Manitoba, and had 23 hours float. It landed near Peace River, Alberta.
