Temperature Modification: Yes, through NKEMOD=0,-1 and TKEMOD=0.150
Density Modification: No
Chi Modification: No
Current to limit q(0) set: Yes, used: No
Comments:
This case fixes bogus TRANSP 2190. It uses 50 rays, TORIC, and equilibrium solver VMEC6.
Reverse shear is maintained until about 0.4s. q(0) drops to 1 at 0.7s. Strong shear is exhibited
throughout. This run has a much higher bootstrap fraction than others, max fbs = 0.25.
For more information about the run see the
input namelist.
The image below plots the total current vs time. Overplotted is the central density. This clearly shows the effect that when the density increases the
LH current decreases, and thus the ohmic current must increase.
Legend:
Total Current: White
Lower Hybrid: Red
Ohmic Current: Green
Bootstrap Current: Blue
Electron Density: Cyan
The figure below shows the actual power spectrum from the TRANSP output.
