Density Profile: Artificial barrier at r/a=0.5, n0~4
Chi Modification: Yes, NKEMOD=0,-1 and TKEMOD=0.15
Noteworthy Switches: NZONES=100, LEVGEO=6(VMEC6),

Comments:

A little chunky at the start up, strange ohmic profile shape. The system is still overdriven and requires jqlim. Lower the power to 1.85MW. Otherwise this run has high maximum bootstrap fraction 66% and an average fbs of 57%. For more information about the run see the input namelist.
