Summary: | The NINA detector on board the Resurs-01 No. 4 satellite (835 km, 98°
inclination) is equipped with particle trackers based on silicon strip
detectors. From the energy deposited in each of its silicon layers the
mass, the momentum direction and energy of incident particles have been
determined. The resolutions in mass and energy allow identification of H and
He isotopes over the 10-50 MeV/n energy range. The angular resolution is
about 2.5°. We present the direct measurements of proton and helium
isotopes pitch angle distributions derived from Resurs-01 No.4/NINA
observations and their variations as functions of (B, L) coordinates and
energy. The measurements of trapped helium isotopes spectrum are also
presented. |
