BASIC STUDIES IN MAGNETOHYDRODYNAMICS.

Abstract

In this investigation, the magnetic annular shock tube (MAST) is developed and used to study plasma phenomena important for collision free plasmas. Studies are carried out to bring the MAST to a state of development where it will become an established research tool. It is found that for a given shock velocity the shock tube must have a minimum length and that the plasma must be contained away from the walls of the tube, this being done by the use of magnetic fields. The annulus ratio and ablation are also important considerations in successful MAST operation. The plasma produced by the shock wave is collisionless in that the mean free path for ordinary collisions is large compared to the shock thickness. However, the importance of collisions in the shock front itself is not clear. (Author)
