Abstract : A plasma wind tunnel facility, similar to that described by Pugh and Patrick, is used to produce a super-Alfvenic flow of plasma over a magnetic obstacle for times approaching one millisecond. The flowing plasma has a density greater than 2 x 10 to the 13th power/cc on axis, and the density has decreased to one-half the peak value at a radius greater than 25 cm. The magnetic field embedded in the plasma stream is primarily axial and less than 30 gauss in magnitude. The magnetic field of the obstacle is essentially that of a single current-carrying conductor located on a diameter of the plasma stream cross section. The field of the obstacle is distorted by the plasma flow, and a narrow transition region forms in front of the obstacle. Preliminary investigations of the properties of the transition region are discussed. (Author)
