Summary
Abstract: The Ultra Low Energy Isotope Spectrometer (ULEIS) measures ion fluxes
over the charge range from H through Ni from about 20 keV/nucleon to
10 MeV/nucleon, thus covering both suprathermal and energetic particle
energy ranges. Exploratory measurements of ultra-heavy species (mass
range above Ni) will also be performed in a more limited energy range
near 0.5 MeV/nucleon. ULEIS will be studying the elemental and
isotopic composition of solar energetic particles, and the mechanisms
by which these particles are energized in the solar corona. ULEIS will
also investigate mechanisms by which supersonic interplanetary shock
waves energize ions.

ULEIS level 2 data is organized into 27-day time periods (Bartels
Rotations - roughly one solar rotation period). For each Bartels
Rotation, the level 2 data contains time averages of energetic charged
particle fluxes over the following time periods:

- hourly
- daily
- 27 days (1 Bartels rotation)

Currently, flux data are available for 7 species, in several energy
intervals for each species. Flux data are in units of particles/(cm2
Sr sec MeV/nucleon).

The species for which data are available are:

- H, 3He, 4He, C, O, Ne-S and Fe.
