The Triana PlasMag Faraday Cup (FC) will be able to determine speed, flow a
ngles, temperature, and density of the main solar wind ion species with a t
ime resolution of better than one second. Thus, the Triana PlasMag FC will
enable resolution of spatial structures as small as a few hundred kilometer
s as the structures convect past the spacecraft. Under typical solar wind c
onditions, that size is comparable to a few proton gyroradii.
