JET_19649_com.dat  ITER Profile Database;  datasets originally prepared 
   by Pam Stubberfield, Bernard Balet and Knud Thomsen JET, March 1995
   and re-issued July 1995.

   JET shot 19649 is a standard L-mode shot obtained after the installation
   of the beryllium limiter. Plasma is deuterium.

   The dataset files in this subdirectory were prepared from TRANSP run 5920, 
   assuming up-down symmetry, run by P.M.Stubberfield on 19 July 1995 on the IBM 
   JAC-2 RS6000 workstation based on JET shot 19649 taken on 3 June 1989. 

   All these files have been prepared according to the Standard list of
   Variables and File Format manual by D.Boucher (24 October 1994). Tools
   to produce these files from a TRANSP run were provided by Glen Bateman,
   Stan Kaye and Ben LeBlanc of PPPL. These have only been modified slightly to
   run on the RS6000 UNIX workstation, to add 40 secs to all time axes and to
   include elongation and triangularity.
   There are 23 1-D Ufiles and 25 2-D Ufiles.  The raw data files for TEXP,
   TIXP etc and the error bar files TEEB, TEIB etc are missing but q profile present. 

   Some 4MW of 80KV/D neutral beam heating is turned on at 46secs
   then at 46.05 secs  the remaining Pinis are switched on giving
   a total of 9.236MW of beam heating.

   In the file JET_19649_0d.dat data is given at two times.
   At 45.50 secs there is no additional heating and the plasma is 
   in a steady ohmic mode . Shortly after this time full heating is 
   switched on and the plasma goes into L-Mode.
   By the second time of 48.70 secs the plasma  is in a steady state.

   The plasma is in belt limiter configuration.
   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 FAST.
        kappa = (Zmax-Zmin)/(Rmax-Rmin);   delta = (RGEO - R(Zmax))/a

   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 5920;
   50ms analysis time resolution; VMEC equilibrium LEVGEO = 5  
   Boundary definition obtained from the FAST program
   Sawteeth events are not taken into account in the simulation.
