  Context: The HELIOS solar observation probes provide unique data regarding
their orbit and operation time. One of the onboard instruments, the Experiment
6 (E6), is capable of measuring ions from 4 to several hundred MeV/nuc.
  Aims: In this paper we aim to demonstrate the relevance of the E6 data for
the calculation of galactic cosmic ray (GCR), anomolous cosmic ray (ACR), and
solar energetic particle (SEP) fluxes for different distances from the sun and
time periods.
  Methods: Several corrections have been applied to the raw data: determination
of the Quenching factor of the scintillator, correction of the temperature
dependent electronics, degradation of the scintillator as well as the effects
on the edge of semi-conductor detectors.
  Results: Fluxes measured by the E6 are in accordance with the force field
solution for the GCR and match models of the anomalous cosmic ray propagation.
GCR radial gradients in the inner heliosphere show a different behaviour than
in the outer heliosphere
