The magnetic field produced by positive and negative pairs of straight line currents placed in a cylindrical configuration creates a magnetic bottle. After a pure plasma is produced inside the magnetic field configuration the current in the coils is increased to adiabatically compress the plasma by the magnetic barrier produced. A pure, highly compressed plasma is obtained with no trapped magnetic field inside. To avoid end losses the current carrying conductors creating the multipolar field must be brought together at the tube end in a configuration similar to the lines of force in a mirror machine. This cylindrical multipolar cusp magnetic field should be useful in ion cyclotron plasma heating experiments to keep the hot plasma away from the wall and thus reduce the impurity levels. (C.E.S.)
