JET_37728_com.dat  ITER Profile Database;  datasets prepared 
   by Pam Stubberfield,  August 1998

   JET shot 37728 is an ELMy H-mode shot obtained in the new JET pump divertor
   configuration. This pulse (2.7T,2.6MA) is part of a series of nu* scaling
   experiments relevant for ITER. Plasma is 93% D, 7% He3.  The plasma is in a single-
   null X-point configuration with the ion gradB drift pointing towards the X-point.
   About 6.5MW of 140KV/D neutral beam heating is turned on from 54 to 59.5 secs 
   and approximately 8.0MW of 80KV/D from 57.0 to 59.0 secs.
   2 MW of RF heating comes on at 57 secs.

   The dataset files in this subdirectory were prepared from TRANSP run N408 
   taking into account the up-down asymmetry of the plasma, run by Bernard
   Balet on 17 August 1998 on the ROSS batch workstation based on JET shot
   37728 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 (4 May 1998). 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 JET
   UNIX workstation and to add 40 secs to all time axes.
   There are 23 1-D Ufiles and 38 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. 2D profiles for Zeff and
   the ICRH power deposition on both thermal electrons and ions is provided.

   In the file JET_37728_0d.dat data is given at 58.12 secs.  At that time,
   there is 13.0MW of NB heating and 2MW of ICRH 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 N408;
   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 total radiation is used in the analysis. 
   Rotation velocity profile from CX measurements is provided.
   Zeff profile from CX measurements; 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 N408 results in a predicted W_dia slightly
   lower than the measured value but higher than that predicted by the
   previous simulation N407 where the RF power was omitted.
   The simulated neutron yield agrees with the measured value at 58.12 secs.
