  Tokamak: ITER

  Pulse number: 20030100
    Scenario = 4 (Hybrid), shot = 003 (high beta_n), modeler = 01 (Budny), try = 00

  Shot description,purpose of the shot: 
    simulation of a high beta_n, peaked profile Hybrid plasma in ITER
    NNBI directed below the plasma axis

  Contact person: Robert Budny

  Institution:  PPPL

  Date of shot: future

  Special times of interest
    950.0 steady-state with 33MW NNBI heating and current drive
    450.0 steady-state with 33MW NNBI and 20MW He3 minority ICRH

  Analysis codes: TSC / TRANSP

  TRANSP run number: 40600A01

  Date of analysis: 20080318 by Robert Budny (budny@princeton.edu) and
  Chuck Kessel

 Assumptions made for analysis:

  TSC generated movie.cdf_iterhyb_02
    toroidal field = 5.3T at R=6.2m
    evolved free boundary, plasma current, and density to steady state around 170s
    pedestal Te and Ti prescribed, GLF23 to predict Ti and Te profiles

  TRANSP run ITER/05 40200A01 used the TSC boundary and plasma and impurity profiles
    50 zones for thermal plasma, ESC for MHD equilibria
    1-MeV D-NNBI of 16.5 MW starting at 50s, stepped up to 33MW at 150s
    20MW ICRH at 52.5 MHz with minority n_He3 / n_e = 2% from 150 to 500s
    D-NNBI is co-directed 40cm below plasma axis with a tengency radius of 5.3m
    Excited-states ionization of the beam neutrals is modeled
    Assumed n_Be / n_e = 2%, n_C / n_e = 2%, n_Ar / n_e = 0.12%
    He4 ash accumulation simulated assuming explicit diffusivity = 1.0 m2/s,
      inward pinch = 1 m/s, and wall/divertor recycling coefficient = 0.7
    Toroidal rotation is modeled assuming the computed NNBI torques and
      chi_mom = chi_i
    NCLASS used for neoclassical profiles

 Additional information:

  beta_n = 3.08, f_Greenwald=0.93, P_DT=528MW
  T_ped=11keV, required by GLF23 in TSC to get high P_DT
  I_Ohmic=4.5MA, I_boot=5.6MA, I_NNBI= 1.7MA
