JET_37718_com.dat  ITER Profile Database;  datasets prepared 
   by Pam Stubberfield,  April 1997

   JET shot 37718 is an ELMy H-mode shot obtained in the new JET pump divertor
   configuration. This pulse (2.0T,2.0MA) is part of a series of nu* scaling
   experiments relevant for ITER. Plasma is 82% D, 18% He3.  The plasma is in a single-
   null X-point configuration with the ion gradB drift pointing towards the X-point.
   Just under 4.0MW of 140KV/D neutral beam heating is turned on from 54 to
   58.0 secs.  Approximately 6.0MW of 80KV/D is switched on at 54.0 secs. At 57 secs
   this power is reduced to 1.2 MW which continues until finally being turned
   off at 58 secs.

   The dataset files in this subdirectory were prepared from TRANSP run M909 
   taking into account the up-down asymmetry of the plasma, run by Bernard
   Balet on 10 December 1996 on the IBM JAC-2 RS6000 workstation based on
   JET shot 37718 taken on 25 July 1996. 
   All these files have been prepared according to the Standard list of
   Variables and File Format manual by D.Boucher (7 December 1995). Tools
   to produce these files from a TRANSP run were provided by Stan Kaye
   of PPPL. These have only been modified slightly to run on the RS6000
   UNIX workstation and to add 40 secs to all time axes.
   There are 23 1-D Ufiles and 35 2-D Ufiles.  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 NM2 and the helium-3 density in NM1.

   In the file JET_37718_0d.dat data is given at 55.38 secs.  At that time, there
   is 9.7MW 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 is from XLOC ; SEPLIM is given by EFIT.
   PLTH is defined by WTH/TAUTH coming directly from TRANSP output and not 
   as defined in the standard list of variables. The 1d files for IP,VSURF 
   and IBOOT have negative values as normal for JET. 
  
   Some comments on this particular TRANSP run M909;
   25ms analysis time resolution; VMEC equilibrium LEVGEO = 6

   No sawteeth events are taken into account in the simulation
   Ti profile  from CX measurements is provided.
   Te profile vs. radius is from LIDAR measurements.
   Ne profile from LIDAR , scaled by FIR interferometer measurements
   1D total radiation is used in the analysis.

   The TRANSP simulation in run M909 results in a predicted W_dia within
   0.2 MJ of the measured value.The simulated neutron yieldis 15% higher
   than measured value at 55.38 secs.
