Summary

The ARCS 3 payload equipped to measure electric and magnetic field fluctuations, and charged particles was launched from Sondre Stromfjord at 0211 UT on 10 February 1985. A subpayload, carrying two argon ion accelerators, was ejected downward and parallel to the magnetic field. The spin axis of the subpayload was aligned along the field so that one accelerator ejected ions, approximately anti-parallel to the field toward the main payload and the other accelerator ejected ions approximately perpendicular to the field. In this paper we present results from our preliminary investigation of the second perpendicular and parallel ion beam injections. The investigation centers on observations from single particle ion detectors and 0 to 10 KHz electric field plasma wave receivers. An ion flux consistent with the expected dectector response due to the argon ion beam was recorded during both the perpendicular and parallel ion beam events as well as an unexpected ion flux at 90° pitch angle during the second parallel ion beam event. The waves observed during the per pendicular events were much stronger than those observed during the parallel events.
