Plasma generates surprising patterns


Designer plasma. A plasma generated by a radio-frequency electric field and subject to a strong magnetic field can form filaments parallel to the fields. With a magnetic field of 1.2 tesla, the filaments merge into complex patterns seen here in a plane perpendicular to the filaments at three different pressures. The work demonstrates an unexpected regime of filamentation as well as a new technique for imaging plasma dynamics.
