Comments:

This run is an artificial density barrier case with a width of 5 cm located at r/a=0.5. 2262 looked promising, except for the small problem of the failure of the equilibrium solver. The LH current looked good and there was a lot of bootstrap. The solver failed because the plasma became too overdriven, creating a too much negative OH current on axis. This run has the LH power reduced to 1.5 MW to try and reduce the problem. The lower LH power indeed helps the ohmic is pretty much positive on axis. Increasing the LH power may keep q(0) above 2. The average bootstrap fraction is 0.28 and peaked at 32%. For more information about the run see the input namelist.
