Two low-beta NSTX discharges that represent the collisionality scan are being analyzed
I have started the analysis of two low-beta H-mode NSTX discharges suggested by Stan Kaye. These discharges are
141031A10 – high collisionality
141040A05 – low collisionality
I have reproduced the old analysis runs. Also, I started to do predictive runs with the Multi-Mode Model MMM7.1:
- 141031P00/141040P00 – analysis runs. The results are the same as in the original TRANSP runs
- 141031P01/141040P01 – FIrst predictive runs with the default MMM7.1 settings. The effect of ExB flow shear in the DRIBM model is disabled
- 141031P02/141040P02 – Number of NZONES is increased from 40 to 80
- 141031P03/141040P03 – The ExB flow shear for DRIBM is enambed. The ExB factors for DRIBM and Weiland are set to the same level:
FACEXB = 0.5 ! factor for ExB flow shear
LMMM07(4) = 0 ! Switch for disabling ExB shear eects in DRIBM model
CMMM07(3) = 0.5 ! ExB shear Multiplier in DRIBM model - 141031P04/141040P04 – The ExB factors for DRIBM and Weiland are set to the default level that is typically used for other tokamaks:
FACEXB = 1.0 ! factor for ExB flow shear
LMMM07(4) = 0 ! Switch for disabling ExB shear eects in DRIBM model
CMMM07(3) = 1.0 ! ExB shear Multiplier in DRIBM model
