Comments:

This is a duplicate of 2373 but with turning on the current diffusion model in LSC. Using a diffusion coefficient of 0.2 m^2/s seems to give very similar results to 2376. The problem of current on axis may be due to to many zones near the axis. If a little power is deposited there by a ray driving a small current then the current density sees a big jump because the area is small. For more information about the run see the input namelist.
