RESEARCH NOTE: Experimental and theoretical observations on a fast linear pinch

Abstract

ABS>A shock-heated linear z-pinch experiment is described, in which an initial B/sub z/ field and strong pre-ionization are employed. The properties of the B/sub z/ and B/sub sub t//sub t/ fields, from the plasma axis to the wall, are found from 0 to 2.5 mu sec after initiation of the discharge. The B/ sub sub t//sub t/ field sweeps the plasma into the central area; a shock is thereby formed in the B, field, which is pushed to the sxis. The observed effects are compared with one-dimensional magnetohydrodynamic predictions. (T.F.H.)
