Azimuthal Current Density Distribution Resulting From A Power Feed Vacuum Gap In Metallic Liner Experiments At 1 MA

We present a study investigating the distribution of current density in solid, metallic liners directly relevant to the MagLIF approach to fusion. Here, the liner thickness is large compared to the collisionless skin depth, and a vacuum gap is introduced in the power feed to simulate the load method on the Z machine at Sandia Laboratories. We present optical emission data along with a 3D magnetic field mapping method from aluminum liner loads on the 1 MA, 100ns COBRA generator.
