IMAX Drawing (10kB) |
IMAX was designed to measure the galactic cosmic ray abundances of protons,
antiprotons, deuterium, helium-3, and helium-4 in the energy range
from ~0.2 to ~3.2 GeV/nucleon. Additionally the University of Arizona used the IMAX scintillators to search for dark matter candidates. For the IMAX flight new driftchambers from Siegen were installed. They had the same dimensionsand the same driftcell structure as the MASS2 chambers, but with additional shaping wires the symmetry of the electric field could be improved. IMAX had a successful flight from Lynn Lake, Manitoba, Canada on 16-17 July 1992, attaining a float altitude of about 36 km for a duration of about 16 hours. Over 3 million triggers were recorded. |
