JET_38407_com.dat  ITER Profile Database;  datasets prepared 
   by Pam Stubberfield,  April 1997

   JET shot 38407 is an ELMy H-mode shot obtained in the new JET pump divertor
   configuration. This pulse (1.5T,1.5MA) is part of a series of beta scaling
   experiments relevant for ITER. Plasma is 80% D, 20% He3.  The plasma is in a single-
   null X-point configuration with the ion gradB drift pointing towards the X-point.
   About 6.0MW of 140KV/D neutral beam heating is turned on from 55 to 60 secs.

   The dataset files in this subdirectory were prepared from TRANSP run N106 
   taking into account the up-down asymmetry of the plasma, run by Bernard
   Balet on 18 December 1996 on the IBM JAC-2 RS6000 workstation based on
   JET shot 38407 taken on 5 September 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 density in NM1.

   In the file JET_38407_0d.dat data is given at 57.40 secs.
   At that time, there is 5.6MW 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 N106;
   25ms analysis time resolution; VMEC equilibrium LEVGEO = 6  
   Up-down asymmetric boundary definition obtained from the EFIT program
   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 measurements 
   1D bulk radiation is used in the analysis. 
   Rotation velocity profile from CX measurements is provided.
   1D Zeff from visible bremsstrahlung; Zimp vs time from CX
   Edge ptcl confinement time is set to 1s.
   Bootstrap current on NLBOOT = T ; impose q(0) = 1.1 to start
   Neoclassical beam driven current
 
   The TRANSP simulation in run N106 results in a predicted W_dia within
   0.1MJ of the measured value.The simulated neutron yield is some 50% higher
   than the measured value at 57.4 secs although neutron levels are very low.
