The EV apparatus was used for the first measurements of transport to
3D thermal equilibrium states, then for measurements of 2D fluid instability
and transport. The 2D fluid program is now being pursued on CamV, where the
one-shot imaging is an immense improvement. Current experiments on EV include
bulk particle transport toward thermal equilibrium in a pure-electron plasma as headed
by Jason Kriesel.
The main strengths of EV are its longtime confinement at low magnetic fields,
and its high accuracy measurements of particle density and temperature. The
latter allow derivation of the particle and heat fluxes. We believe these
measurements will continue to be a useful adjunct to the high accuracy
particle density measurements of CamV, and to the non-destructive particle
density and temperature measurements on ions in IV.
