JET_26095_com.dat  ITER Profile Database;  datasets prepared 
   by Pam Stubberfield, Bernard Balet and Knud Thomsen JET, February 1995

   JET shot 26095 is one of the series of hot-ion pulses achieved
   during the first tritium experiments in JET during November 1991.

   The dataset files in this subdirectory were prepared from TRANSP run 0480, 
   assuming up-down symmetry, run by B.Balet on 12 December 1994 on the IBM 
   JAC-2 RS6000 workstation based on JET shot 26095 taken on 4 November 1991. 

   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 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 22 1-D Ufiles and 18 2-D Ufiles.  The raw data files for TEXP,
   TIXP etc and the error bar files TEEB, TEIB etc are missing. 

   Some 4MW of 140KV/D neutral beam heating is turned on at 50 secs then at 51 secs 
   Pinis 3 and 4 on Octant 8 are switched on with 2MW of 80KV/D beams. Pini 6 
   containing a mixture of 12.97KW 78KV/T together with 0.9MW of 80KV/D is also
   switched on.  At 52 secs the remainder of the PINIs are switched on with 140kV/D
   beams to give a total of 14.2MW of beam heating.  At 53.72 secs the ratio of average
   T to D + T density is 0.07%.  At 51.3 secs the plasma changes to X-point formation 
   which causes a sharp increase in the 1d signals for Q95 and LI.

   In the file JET_26095_0d.dat data is given at two times.
   Although all the auxiliary heating has been switched on at 52.22 secs
   the plasma is still in L-mode and the plasma is not in steady state as the 
   plasma energy is rising steadily. Shortly after this time the plasma 
   goes into H-Mode and then into VH-Mode.  By the second time of 53.72 secs 
   the plasma has returned to H-mode.
   As there is no facility at present for 3 beam species in the 0d file the T 
   has been omitted. BGASA and BGASZ correspond to the 140KV/D beams as these
   are the majority while BGASA2 and BGASZ2 correspond to the 80KV/D.
   The value for THNT in the 1d file is for total thermal neutrons (DD + DT).

   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 IDENTC2.
        kappa = (Zmax-Zmin)/(Rmax-Rmin);   delta = (RGEO - R(Zmax))/a

   Values for XPLIM are from the XLOC program and those for SEPLIM from IDENTC2.
   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. BT is negative as the pulse was with reversed toroidal field.
