 Additional information:

  JET shot 35156 is an ELMy H-mode shot obtained in the new JET pump divertor
  configuration. This pulse ( 2T, 2MA ) is part of a series of rho* scaling 
  experiments relevant for ITER. Plasma is deuterium.  The plasma is in a single- 
  null X-point configuration with the ion gradB drift pointing towards the X-point.
  Re-processed NBI data giving approximately 10% more power in the 140kV/D beams
  was used in the TRANSP simulation.  Some 1.4MW of 80KV/D neutral beam heating is
  turned on at 52 secs.  Then at 54.5 secs, the remaining Pinis are switched on
  giving a total of 8.8MW of beam heating ( 1.9MW of 140kV/D and 6.9MW of 80kV/D ).

  In the file JET_35156_0d.dat data is given at 15.80 secs  at the top of
  a sawtooth.  At that time, there is 8.8MW of beam heating and the plasma
  is in a steady ELMy H-mode phase. 


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

  In jet_35156_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_35156_0d.dat data its given at 16.61 secs.
  At that time, there is 11.5MW of beam heating and the plasma is 
  in a steady ELMy H-mode phase. 

  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 - R(Zmax))/a
  XPLIM and SEPLIM from XLOC
  as defined in the standard list of variables. The 1d files for IP,VSURF 
  and IBOOT have negative values as normal for JET.

  25ms analysis time resolution for the ESC equilibrium (LEVGEO = 7).
  Up-down asymmetric boundary definition obtained from the EFIT program
  
  Ti, v_phi, and Z_eff profiles from CX measurements.
  Te and Ne profiles vs. radius is from LIDAR measurements.

  Edge recycling and gas puffing used for particle balance to compute
  particle fluxes.
 
  The TRANSP run 35156C02 gives a simulated W_dia 8% lower than
  the measured and a simulated neutron yield agrees well with the
  measured rate.
