Verification and validation of electromagnetic instabilities from XGC1 in NSTX and NSTX-U plasmas
POSTER
Abstract
Electromagnetic instabilities will be investigated in the NSTX and NSTX-U plasmas, including edge pedestal area, using the gyrokinetic code XGC1. Cross-verification will be performed with other electromagnetic gyrokinetic codes. Results will be compared with experimental diagnostics data. Relation of the gyrokinetic instabilities to the edge localized instabilities and the maximal pedestal height-gradient will be discussed.
