Abstract

We have positively identified sixteen mass-resolved cosmic ray anti.protons with energies between 0.2 and 3.2 GeV using the IMAX balloon-borne magnetic spectrometer. Mass was determined by velocity vs. magnetic rigidity techniques using a high resolution time-of-flight system and silica-aerogel Cherenkov detectors. The anti.protons are clearly separated from the low-mass particle background. Here the measurement technique, data analysis, and resulting proton and antiproton mass histograms are presented.
