Particle Fluxes Associated with Solar Flares.
Abstract
An investigation of particle fluxes associated with solar flares was carried out with rocket-borne instrumentation. Two instruments were flown on each of six NIKE Javelin rockets from Ft. Churchill, Canada subsequent to the onset of the PCA event of November 1969. The first instrument consisted of a three-counter telescope detecting electrons, protons, alphas, and gamma rays. Data were obtained at altitudes of about 40 to 130 kilometers with seven logic outputs representing various energy intervals for electrons, protons, alpha particles, and gamma rays. Flux variations with time are observed over a period of about 50 hours and are compared with available satellite data. The second instrument contained a silicon avalanche detector designed for low-energy electrons. A magnetic field is cyclically applied to separate low-energy electrons from high-energy particulate or photon radiation. From this instrument is obtained count rate and spectral data for low-energy electrons. Comparisons of four separate launches are made to demonstrate the flux variation over a period of several days.
