 Tokamak: JET

 Pulse number: 60927

 Shot description, purpose of the shot: 
   Hybrid scenario at 1.7T/1.4MA, high triangularity, D2 gas puffing during
   heating phase, "compound" type 1 ELMs, no sawteeth, pair of 60931

 Contact persons: Robert Budny, Irina Voitsekhovich, Ian Jenkins, Frederic Imbeaux,
    Emmanuel Joffrin

 Institution: EFDA-JET

 Date of shot: 20040210
 
 Time of interest = 9.5s (49.5s in JET PPF time) for steady state,
   1-12s for high power phase

 Analysis codes: TRANSP, EFIT for plasma boundary

 TRANSP RunID 60127C03 done at PPPL, stored at JET and on mdsplus server

 Date of analysis: 20080319 by Robert Budny(budny@princeton.edu)
   This resubmission fixes QICHRE and QICHRI
 
 Assumptions for analysis:

  Te and ne profiles from LIDAR measurements.
  Ti, toroidal rotation, Z_eff profiles from CX measurements
  Up/down asymmetric boundary and q-profile given by EFIT.

  TRANSP computes the central q to droop below unity, but no sawtooth are evident
  so the q_profile estimated by EFIT was used as input.

 Additional information:

  Pulse 60927 was conducted under the S2 Task Force to investigate the hybrid scenario

  The auxilliary heating consisted of D-NBI with power ramped up to 13.4MW from 4 to 14s
  and about 1.0 MW H-minority ICRH from 4.0 to 14.0s
  The antenna phasing was -90,+90,-90,+90 degrees
  There was approx 1.2MW of LHCD from 1.8 to 6.0s

  The ICRH was modeled using New SPRUCE
  The LHCD was modeled using LSC

  The direction of the toroidal field and plasma current were in the
  normal JET direction - clockwise viewed from above.
  The NBI voltages were 105 keV for 6 beams, 90 for 2, and 80keV for 5

  Argon and neon was injected into the plasma for diagnostic purposes.
  The measured densities were inputed into TRANSP

  All calculations have been done on a 50 zone radial grid.

  Most quantities have been smoothed to suppress statistical noise. 

  In the jet_60927_2d.dat file thermal D is stored in NM1, trace T is
  stored in NM2 and the lumped impurity density in NM3.

  In the file jet_60927_0d.dat data is given at 9.5 secs.
  XPLIM is from XLOC; SEPLIM is given by EFIT.
  DELTA is the average of the upper and lower triangularities.

  Good agreement was found for W_dia comparing TRANSP, EFIT, and XLOC
  (differences 0.5%).
  The simulated DD neutron rate is high x2.
  The volume-averaged Z_eff from CX data is 60% below the bremsstrahlumg
  measurements along the central vertical chord.
  The difference in density measurements between LIDAR and interferometry
  is within 8.5%
