Ml. Ambriola et al., CAPRICE98: A balloon borne magnetic spectrometer to study cosmic ray antimatter and composition at different atmospheric depths, NUCL PH B-P, 78, 1999, pp. 32-37
CAPRICE98 is a superconducting magnetic spectrometer built by the WiZard co
llaboration. It was launched from Ft. Sumner, NM, USA on the 28th of May 19
98. For the first time a gas RICH detector has been flown together with a s
ilicon electromagnetic calorimeter. The instrument configuration included a
time of flight detector and a drift, chamber stack, which were placed in t
he region of a magnet field, for rigidity measurement. Science objectives f
or this experiment include the study of antimatter in cosmic rays and that
of cosmic ray composition in the atmosphere with special focus on muons.
