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
