  1. Transport Code(  Thoughts, actions for use of, linkage to PDB) M.Yokoyama

  2. On Use of PDB (by transport codes) • Compatibility (readability) of 2D Ufiles • checked by TASK3D(Sato), IPP (Turkin) and ASTRA (Estrada) (Apr. 09) • NC database for transport module • (specific-physics in helical systems: particularly important for transport analysis) • Extension of DCOM/NNW : vacuum to finite beta, lower collisionality • (Wakasa, Yokoyama) • Equilibrium Data • equilibrium information corresponding to registered shots • Some examples for W7-AS high-beta shots: 54022, 54023 (Geiger) • triggering comments/demands/usability investigation ! (boost the discussions) • inputs from LHD high-beta talks (this afternoon)

  3. NC database for NC module • We should equip NC DB to be applicable to (at least) registered shots • Moreover, DB covering a wide range of parameters are required • Certainly not enough at one specific radius • DCOM/NNW has been one of attempts to deliver NC DB to transport codes • (A.Wakasa et al., JJAP 46 (2007) 1157.) • It has been extended to • Lower collisionality (where Monte-Carlo gets so time-consuming) (M.Yokoyama) •  Increased accuracy of NNW (DGN/LHD, ITC18(2008)) to be applicable to low-collisional plasmas (eg., CERC) • finite beta equilibrium (utilizing the LHD VMEC-DB) (A.Wakasa) • <> ~ 1, 2, 3 % of Rax,vac=3.75m, 3.60m  NNW wrt <>, covering wide range of  values

  4. Extension towards low-collisionality, finite  (training data for NNW) Rax,vac=3.75m, =0.5 b100 (~1%) • D* agrees in this range of  b199 (~2%) b298 (~3%)

  5. Extension towards low-collisionality, finite  (training data for NNW) Rax,vac=3.75m, =0.9 b100 (~1%) • D*@Er=0 becomes to differ as  is increased (smaller in GSRAKE, limited Bmns) • However, D* at finite Er agrees well (can be “practically” applicable to experimental analysis) b199 (~2%) b298 (~3%)
