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 nucleon−1. Aims. In this paper we aim to demonstrate the relevance of the E6 data for the calculation of galactic cosmic ray (GCR), anomalous 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.

Scattering Measurement

In this study, we deploy and compare spectrum processing methods based on gamma scattering technique to determine the interface between insoluble fluids stored in the container. The gamma scattering measurement system included: a 5 mCi radioactive source of 137Cs, a cylindrical glass vase with a diameter of 6.5 cm containing the fluids, and a NaI(Tl) detector with a 7.62 × 7.62 cm scintillation crystal. The detector was arranged to obtain the scattered photon beam at the angle of 120o. Two of the three processing methods showed good results with the biggest difference of 5 mm. In addition, the results also show the feasibility of using SCA in gamma scattering measurement system to determine the interface between insoluble environments.

Accelerator System

Measurements are discussed in which the technique of accelerator mass spectrometry was applied to problems involving heavy radioisotopes. These measurements, which depend on the ion energies that can be reached with the new heavy-ion accelerator facilities, were performed at the Argonne tandem linac accelerator system (atlas) and at the unilac accelerator at GSI. The topics include a discussion of measurements of long nuclear lifetimes, of radioisotope detection of interest to solar neutrino experiments, and of a determination of the 41 Ca concentration in natural samples of terrestrial origin by m aking use of isotopic pre-enrichm ent in an isotope separator. A long-known m ethod of isobar separation, employing a gas-filled m agnetic field region, has been revived for some of these m easurem ents and its characteristics and advantages are briefly reviewed.
