Presentation Transcript

  1. Transient Transport Working Group • Emphasis moved from technique to results • Regular contributions to particle and electron thermal transport

  2. Ryter: Complementary power balance and modulated ECH results on ASDEX-U and other machines; new two-point heating to maximize change in gradient • Measure of Qe(Te) from DIII-D • Wade: Necessity of time-dependent perturbation analysis for particle transport to separate D,V

  3. Comment on Density Evolution n to t If t = 1/[d(ln(n)/dt] large; interpretation ambiguous • Jump at to to much smaller D; slow evolution to new equilibrium • Slow evolution in D and/or V beginning at to Need response to known (fast) forcing

  4. Future Work • More particle transport experiments • Continuation of modulated ECH experiments including ingenious refinements • Modulation of other localized electron heating modes • Possible ion heating experiments -- not through fast ions
