 Tokamak: JET

 Pulse number: 53028

 Shot description,purpose of the shot: 
   ELMy with X-point in septum, low triangularity
   Companion of 53030 with Ar injection

 Contact persons: Robert Budny, Jef Ongena, Xavier Garbet

 Institution:  EFDA-JET

 Date of shot: 20010111

 Time of interest = 21.5s (61.5s in JET PPF time) for steady state

 Analysis codes: TRANSP and EFIT (for plasma boundary)

 Run number: 53028C05 at PPPL, available on mdsplus

 Date of analysis: 20051031 TRANSP run by Robert Budny (budny@princeton.edu)

 Assumptions made for analysis:

  Te and Ne profiles vs. radius from LIDAR measurements.
  Ti, toroidal rotation velocity, and Z_eff profiles from CX measurements.
  The radiation emission profile was derived from inverting two bolometry views.
  Particle confinement time is calculated from source rates.
  Sawtooth breaks were deduced from T_ece (KK3/TE45) up to 20.4s,
  No sawteeth are indicated later, presumably due to the central q increasing
  above unity.
  The q profile was calculated in TRANSP from the sawtooth mixing model and
  poloidal field diffusion.
  The central q drops below unity, apparently due to inadequacies in the sawtooth
  model or due to the central Z_eff being higher than modeled from the C impurity..

 Additional information:

  The direction of the toroidal field and plasma current were in the
  normal JET direction - clockwise viewed from above.

  The NBI voltages were 138 keV for 8 beams and 80keV for 6.

  All beam related quantities (energy, particle sources, currents etc) 
  have been smoothed to suppress Monte-Carlo noise. 
  In the 2d file the deuterium density is stored in NM1. 
  In the file JET_53028_0d.dat data is given at 21.50 secs. 
  In the file JET_53028_2d.dat data NM1, NM2, and NM3 are the caclulated
  densities of D, trace H, and trace T 
  NM4 is the trace carbon impurity.

  Values for kappa and delta in the 0d, 1d and 2d files are from the TRANSP
  output derived from the boundary input provided by EFIT.
  kappa = (Zmax-Zmin)/(Rmax-Rmin),   delta = (RGEO - min(R(zmin),R(Zmax)))/a
  XPLIM and SEPLIM are given by EFIT.
  as defined in the standard list of variables.  
  
  The TRANSP run gives a simulated W_dia 10% above the measured value
  and a neutron emission rate 20% above the measured value.
