Full-f electromagnetic simulation of a helical model scrap-off-layer plasma. Shown are the density (left) and temperature (middle) for electrons (top) and ions (bottom). The dashed line is where the source terms are applied. Intermittent blob-like structures are seen that are ejected from the source region and propagate outwards.  The right figure shows magnetic field lines in a (radial, vertical) projection being bent by blobs near the midplane (at an earlier time t=240 μs). Note the z and x axes are not to scale, rms dB/B~10%
