 Tokamak: JET

 Pulse number: 55935

 Shot description,purpose of the shot: 
   ELMy with detailed edge measurements

 Contact persons: Robert Budny (budny@princeton.edu), Jef Ongena, Xavier Garbet

 Institution:  EFDA-JET

 Date of shot: 20020521

 Time of interest = 19.7s (59.7s in JET PPF time) for steady state

 Analysis codes: TRANSP and EFIT (for plasma boundary)

 Run number: 55935C14 at PPPL, available on mdsplus

 Date of analysis: 20051107 TRANSP run by Robert Budny
   Resubmission updating variables

 Assumptions made for analysis:

  Up/down asymmetric boundary given by EFIT.
  Ti, toroidal rotation velocity, and Zeff profiles from CX measurements
  during NBI between 17.4-25.0s and major radius=3.05-3.86m.
  (x = sqrt. normalized toroidal flux=0.25 and 0.8).
  Ti extrapolated to Te before x=0.25 and beyond x=0.8
  Te and Ne profiles vs. radius from LIDAR measurements.
  The radiation emission profile was assumed to be flat.
  Particle confinement time is calculated from source rates.
  q profile calculated in TRANSP from poloidal field diffusion.

 Additional information:

  Pulse #55935 was constructed to have extensive edge diagnostics.

  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 4 beams, and 80keV for 5

  Most quantities have been smoothed to suppress statistical noise.
  
  In jet_55935_2d.dat the deuterium density is stored in NM1, trace H in NM2,
  and trace T in NM3. 
  NM4 contains the carbon density being the majority impurity species. 
 
  In the file JET_55935_0d.dat data is given at 19.70 secs. 

  Values for kappa and delta in the 0d, 1d and 2d files are from the TRANSP
  output derived from the boundary input definition 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 20% above measured.
