O. ; Lockwood, J. A. Abstract Observations of the solar H-alpha, radio, and hard X-ray radiation and measurements made with the gamma-ray spectrometer on the Solar Maximum Mission satellite, the Goddard cosmic-ray detector on Helios 1, and the Jungfraujoch neutron monitor during the solar cosmic-ray event on June 3, 1982 were used to determine the onset times of the various electromagnetic emissions, the injection of the flare protons into the interplanetary magnetic field, and the production of solar neutrons. The results of this analysis show that the time to accelerate the first protons up to energies of a few GeV was about 3.5 minutes longer than the time needed to accelerate the first 20 MeV protons. The accelerations process of the high-energy protons in this event is consistent with the conventional picture of solar flare particle acceleration where energy is dissipated from the flare region, heating the coronal plasma and producing a strong shock wave. The shock, as it then moves through the corona, accelerates the higher energy protons.
