MAGNETIC SPECTROMETER

Developed by NASA - Goddard Space Flight Center (GSFC)

Balloon launched on 7/15/1974, from Fort Churchill Airport, Manitoba, Canada

Purpose of the flight and payload description

The apparatus, uses magnetic-core digital spark chambers to determine the trajectories of charged particles through the instrument, before and after they pass the gap of a permanent magnet. The direction and magnitude of the magnetic deflection provides the sign and rigidity of each particle traversing the detector. The spark chambers are triggered by a counter telescope consisting of a directional gas Cerenkov counter and two plastic scintillation counters. In addition, two anti-coincidence scintillation counters are used to veto events in which a particle fails to pass through the magnet gap.
