 Tokamak: JET

 Pulse number: 53030

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

 Contact persons: Robert Budny (budny@princeton.edu), 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: 53030C13 at PPPL, available on mdsplus

 Date of analysis: 20051022 TRANSP run by Robert Budny
   This is a resubmission including PRES

 Assumptions made for analysis:

  Te and Ne profiles vs. radius from LIDAR measurements.
  Ti and toroidal rotation velocity profiles from CX measurements.
  Z_eff is calculated from measured C and Ar densities.
  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 up to 20.4s, and after, EFIT/QMAG was used
  Without using EFIT, 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.

 Additional information:

  Pulse #53030 was was an ELMy RI mode shot with Ar inj.

  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 6 beams and 80keV for 7.

  All beam related quantities (energy, particle sources, currents etc) 
  have been smoothed to suppress Monte-Carlo noise. 
  In the 2d file the trace H density is stored in NM1, the deuterium density
  in NM2, and trace T in NM3. 
  The measured impurity C and Ar are combined in NM4
  In the file JET_53030_0d.dat data is given at 21.50 secs. 

  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 15% above the measured value
  and a neutron emission rate 25% above the measured value.
