The work covered by this report is part of an experimental program to study oblique shock waves in plasma. The support from DASA under this contract was for the continuation of the experimental program with particular regard to measurements on shock using light scattering techniques. The measurements made on the Texas oblique shock experiment were first detailed investigation of the magnetic and electronic structure of the oblique shock. Compared to the fairly extensive body of information which exists on shocks moving perpendicular to the magnetic field, there had previously been only very scanty results on oblique shocks. This was largely because the oblique shock has a larger scale length approx. comega sub pi than the perpendicular shock approx. comega sub pe, and consequently experiments designed from the onset to study the oblique shock, and was significantly larger in scale 50 cm diameter than most shock experiments. The experiment has yielded unique information about the structure of oblique shocks.
