Presentation Transcript

  1. Physics Analysis Progress and PlansS. Kaye 2/7/07 • Meetings • EPS (7/07) and TTF (4/07) contributed abstracts being developed (due 2/13) • Gorelenkov is giving Invited talk at EPS on NSTX/JET Acoustic Alfvén modes • Publications – since last LMR • 2 PRLs in review (and re-review) • Kaye – Transport • Fredrickson – Cascade modes • IAEA papers submitted to Nuclear Fusion special issue • One will miss deadline for special issue • APS Invited papers under (re-)review as well • NSTX Colloquia being given • Wong – UC Irvine (1/26) • Sabbagh – U Wisc. (2/5/07) • Gates – Columbia (early Feb), MIT (early March) • Menard – NYU (Feb) • Kaye – LLNL, UCLA (2/21-22/07), Lausanne, Garching (5/10-11/07) • M. Bell – U. Texas (3/07) • R. Maingi – Georgia Tech (4/07) • R. Raman – U. Rochester, U. Maryland (TBD) • GA, UCSD (TBD – most likely right before or after TTF in S.D.)

  2. First round TRANSP analyses complete for 2006 data (Kaye) • Round 2 to begin • Gyrokinetic analyses being performed on H-mode and RS L-mode plasmas • GYRO non-linear runs give ETG-driven transport levels comparable to those estimated in TRANSP in L-mode plasmas outside region of RS (Mikkelsen) • ETG stable in RS region • Linear GS2 indicates microtearing important; supported by analytic calculations (Wong) • Non-linear electromagnetic GS2 runs to study microtearing are running (Kaye, Mikkelsen)

  3. GTC can now determine kr spectrum of unstable modes for direct comparison to high-k scattering (Wang) • Capability tested on pure ITG modes in RS L-mode plasma (would be stabilized with inclusion of ExB shear) • GEM code still in process of being benchmarked (Rewoldt) • Could be used to study microtearing when ready • Coupling of NMA to DCON to simulate finite resistivity shell, f/b coils and sensors for RWM studies underway (Chance/Sabbagh) • Plans for using HYM to model chirping of GAE/CAE modes on NSTX (Belova) • Error field studies using M3D planned (Breslau/Menard) • BOUT studies of NSTX density scans and blobs (Umansky/Soukhanovskii/Maingi/Zweben) planned • Code still being checked out • Will first attempt density scan simulation
