The Solar Isotope Spectrometer (SIS) is designed to provide high resolution measurements of the isotopic composition of energetic nuclei from He to Ni (Z=2 to 28) over the energy range from ~10 to ~100 MeV/nucleon. over the charge range from H through Ni from about 20 keV/nucleon to The GCRs (Galactic Cosmic Rays) consist, by number, primarily of For the 27-day Bartels Rotation averages, two kinds of averages Release Notes for details. cosmic ray measurements carried out by CRIS. 21 0 obj << /Linearized 1 /O 23 /H [ 820 288 ] /L 115402 /E 90578 /N 5 /T 114864 >> endobj xref 21 19 0000000016 00000 n
