Variations of cosmic ray intensities during the first part of the Helios-I mission

  • 1. Kiel Univ. (F.R. Germany). Inst. fuer Reine und Angewandte Kernphysik

Description

On Dec. 10, 1974, Helios-I was launched into a heliocentric orbit and reached its first perihelion at 0.309 AU on March 15, 1975. The University of Kiel cosmic ray experiment on board measures protons and heavier nuclei with energies between 1.3 and several hundred MeV/N, and electrons above 0.3 MeV of solar and galactic origin. A short instrument description is given, followed by a presentation of daily mean intensities covering the time period from launch to shortly after the first perihelion. Solar particle events are identified and references are given for further discussions. (orig./WL)

Abstract (German)

Helios-1 wurde am 10. Dezember 1974 in eine heliozentrische Umlaufbahn gebracht und erreichte bei 0,309 AU am 15. Maerz 1975 erstmals Sonnennaehe. Das an Bord befindliche kosmische Strahlungsexperiment der Universitaet Kiel misst Protonen und schwerere Kerne mit Energien zwischen 1,3 und mehreren hundert MeV/N sowie Elektronen solaren und galaktischen Ursprungs ueber 0,3 MeV. Auf eine kurze Instrumentenbeschreibung folgen Angaben ueber die mittleren taeglichen Intensitaeten von Beginn des Experiments an bis zum ersten Perihelion. Ereignisse mit solaren Teilchen werden identifiziert, und es werden Angaben zur weiteren Diskussion gemacht. (orig./WL)
