A campaign studying the formation and stability FRC plasmas has been in progress in the Magnetic Reconnection eXperiment (MRX). These FRCs are formed by the counter-helicity merging of two spheromak plasmas, a technique pioneered at the TS-3 device  and recently utilized at SSX. These experiments were made possible by a recent upgrade to the MRX device, including extensions to the vacuum vessel, new â€śShaping Fieldâ€? magnets, upgraded power supplies, and installation of a copper center-column to passively stabilize the spheromaks during formation and translation. Utilizing the flexibility of the MRX coil-sets, we have the ability to create plasmas with range of different separatrix shapes (0.8
