Welcome to the MMS HPCA Science Operations Center!
The Magnetospheric Multiscale (MMS) mission is a Solar Terrestrial Probes mission comprising four identically instrumented spacecraft that will use Earth’s magnetosphere as a laboratory to study the microphysics of three fundamental plasma processes: magnetic reconnection, energetic particle acceleration, and turbulence. These processes occur in all astrophysical plasma systems but can be studied in situ only in our solar system and most efficiently only in Earth’s magnetosphere, where they control the dynamics of the geospace environment and play an important role in the processes known as “space weather.”
Hot Plasma Composition Analyzer (HPCA): The HPCA employs a novel RF technique to measure minor ions such as oxygen and helium in regions of high flux.
Energy range = ~10 eV to 30 keV; energy resolution = 20%; time resoluton = 15 s.
HPCA development is led by Co-I Dr. Stephen Fuselier.
This website is for internal use by the HPCA science team; however, there is a public webpage for the MMS project.
HPCA teams members can use this site to get access to the latest data as well as generate quick look survey plots and see the health and safety of the instruments.
