Abstract : The IMP Satellite magnetic field measurements in the vicinity of the earth's magnetopause has shown that there is a standing shock between the earth's magnetic field and the solar wind, and a flow between the shock and the magnetosphere which is like a continuum flow. A theory which describes the boundary between this flow and the magnetosphere has been developed which shows that the diffusion of the magnetic field lines associated with the solar wind into the earth's magnetosphere can be much larger than previously expected. This has generated an interest in this Laboratory to build a facility which produces a steady flow of high conductivity, collision-free plasma with a characteristic flow dimension large compared to the ion gyro radii. A description of this facility and the design criteria will be given. The results of the calculation of the plasma flow in the field annihilation region between the solar wind and the magnetopause will be briefly reviewed, and the most recent experimental results obtained in the plasma wind tunnel facility will be given.
