Presentation Transcript

  1. Electron transport Discussion • 1. Gyro-kinetic calculations and comparison with experiment • TEM-driven heat flux can be reproduced by non-linear GK calculations • sensitive with experimental uncertainties • contribution from ETG • simultaneous match of qi, qe and  • Whole turbulence k range needed for better assessment?

  2. 2. Micro-tearing modes • MAST/NSTX: • Main contribution to e-transport in MAST and NSTX Yes? • Further assessment required ? low k turb. measurement? • Joint experiments? • Standard tokamaks: • GK calculations suggest -tearing contribution at high  • Can they be identified, separated from ITG? • Identify best suited plasmas: high , ITG stable • Possible Joint Experiments? • Device size adding information? • Complementary information by combining devices (AUG/DIII-D)

  3. 3. Electron transport by Alfvenic modes • NSTX/MAST: • role identified • Joint experiments? • Standard tokamaks: • Is operational/physics domain accessible?
