TRANSP 2238

Power Spectrum

Comments:
This case modifies the density profile of TRANSP 2195 to include an H-mode. Central density is kept low to see if this case will work. It uses 50 rays, TORIC, and equilibrium solver VMEC6. Reverse shear is maintained throughout. q never drops below 2. The average bootstrap fraction is 0.175. The next step is to increase the central density and make a more realistic C-Mod H-mode density profile. For more information about the run see the input namelist.


The image below plots the total current vs time. The current is mostly supplied by LH.
