Results of an experimental study of the flow structure in the region of reattachment of a supersonic laminar separated flow are reported. The separated flow is generated by a model shaped as a compression corner consisting of a horizontal flat plate followed by a ramp. The model with is equal to the plate length from the leading edge to the plate/ramp junction line. The ramp angle is varied in the interval phi = 20deg - 50deg. The free-stream Mach number is equal to 6 or 8. The analysis of the
