   JET_35156_com.dat  ITER Profile Database:  datasets originally prepared 
   by Pam Stubberfield, Bernard Balet and Knud Thomsen JET, August 1995
   but re-issued for the second time by PS in July 1996.

   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 ).

   The dataset files in this subdirectory were prepared from TRANSP run I624 taking 
   into account the up-down asymmetry of the plasma, run by BB on 23 January 1996
   on the IBM JAC-2 RS6000 workstation based on JET shot 35156 taken on 17 May 1995. 
   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 recently updated by Stan Kaye of PPPL.
   These have only been modified slightly at JET 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 31 2-D Ufiles.  Variables GRHO1 and GRHO2 are now stored
   on flux boundaries and 2-D profiles for CURTOT, NM1(D), NIMP, VROT, BPOL
   and QOHM are included.

   In the file JET_35156_0d.dat data is given at 55.80 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. 

   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 I624:
   25ms analysis time resolution: VMEC equilibrium LEVGEO = 6  
   New up-down asymmetric boundary definition obtained from the improved
   EFIT program. 
   Sawteeth events are taken into account in the simulation for redistribution
   of the fast ions and of the current.
   Ti profile from CX measurements.
   Te profile vs. radius is a combination of the ECE and LIDAR measurements.
   Ne profile from LIDAR measurements, mapped on the outer half of the
   plasma mid-plane.
   Radiation is taken into account in the analysis. 
   Rotation velocity profile from CX measurements is provided.
   1d Zeff from VB: impurity species assumed to be carbon
   Edge ptcl confinement time is set to 1s.  Bootstrap current. 
   q(axis) = 1.1 imposed to start.  Neoclassical beam driven current
 
   The TRANSP simulation in run I624 results in a predicted W_dia  
   within 0.1MJ of the measured value.
