  Tokamak: JET

  Pulse number: 49687

  Shot description,purpose of the shot: 
     ELM TypeIII-I power scan

  Contact persons: Robert Budny, Jef Ongena, Xavier Garbet

  Institution:  EFDA-JET

  Date of shot: 19991129

  Time of interest = 24.0s (64.0s in JET PPF time) for steady state

  Analysis codes: TRANSP and EFIT (for plasma boundary)

  Run number: 49687C20

  Date of analysis: 20051107 by Robert Budny (budny@princeton.edu)
  This is a resubmission with new variables

 Assumptions made for analysis:

  Up/down asymmetric boundary given by EFIT.
  Ti and toroidal rotation velocity profiles from CX measurements.
  Both the core (CXSM) and edge (CXSE) measurements were combined.
  Te and Ne profiles vs. radius from LIDAR measurements.
  Density of 2 impurity species (Be, and C) were used to produce a Zeff profile. 
  The radiation emission profile was derived from inverting two bolometry views.
  Particle confinement time is calculated from source rates.
  q profile calculated in TRANSP from poloidal field diffusion.

 Additional information:

  Pulse #49687 was heated near the threshold for Type I<->III transitions,
  and transitioned both ways with a large change of energy and density
  confinement.

  The Ti, rotation, and Zeff profiles were measured from 17 to 22.3s
  between R=2.95 and 3.81m.

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

  All beam related quantities (energy, particle sources, currents etc) 
  have been smoothed to suppress Monte-Carlo noise. 

  In jet_49687_2d.dat, trace H is stored in NM1, deuterium in NM2, 
  and trace tritium in NM3. 
  NM4 contains the carbon density being the majority impurity species. 

  In the file JET_49687_0d.dat data is given at 24.0 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 5% above the measured value
  and a neutron emission rate 80% above the measured.
