Abstract

The Swarthmore Spheromak Experiment (SSX) produces a large s FRC by merging counter-helicity spheromaks within a cylindrical flux conserver. Past results have shown that the toroidal fields in each spheromak do not annihilate even after the poloidal flux appears to have completely reconnected. This would suggest a radially directed current density at the midplane, and therefore a radially sheared azimuthal component of J × B. In contrast, fast high resolution spectroscopic measurements indicate that flow at the midplane is small (u < < v _A ) and there is little shear.
