The structure of MHD switch-on shocks propagating along a magnetic field into an upstream partially ionized plasma is studied experimentally and theoretically. Detailed measurements of density, temperature and magnetic field are presented, and compar

A ruby-laser Thomson-scattering system, designed for very low--electron-density applications, has shown electron temperature (T/sub e/) and density (n/sub e/) profiles in the Elmo Bumpy Torus--Scale toroidal plasma to be flat, with T/sub e/ values fr

Experiments with 200 kW of applied electron cyclotron heating (ECH) power have demonstrated electron temperatures of about 1 keV in the ELMO Bumpy Torus-Scale (EBT-S) device. Electron densities are in the range of (0.5-1.5)*1018 m-3 and increase as t

A ruby‐laser, Thomson scattering diagnostic for electron temperature (Te) and density (ne) measurements has operated on EBT‐S. This is significant because the density is of order or less than 1012 cm−3, because the temperature is a few hundred

A normal ionizing shock wave is one which propagates, with its shock front perpendicular to a steady magnetic field, into a neutral gas producing ionization. In the experiments described a cylindrical shock tube of length 170 cm and diameter 21.4 cm

An experimental study of the structure of an MHD switch-on shock propagating into an almost fully ionized helium plasma is described. It is found that electrons are heated in preference to ions.

Measurements on a reverse biased transverse MHD shock wave show that very high electron temperature and density are produced in the current layer where the magnetic field reverses direction.

An experimental study of the structure of a normal ionizing shock in helium suggests that the shock is essentially resistive with the major dissipative mechnism being ohmic heating of ions and neutrals by ion currents.
