 Tokamak: TFTR

 Pulse number: 55851

 Shot description, purpose of the shot: 
   55806 as the record D_DD of a non-disruptive TFTR discharge.
   meas fusion yield=3.82E16/8.55E17=0.04468 MW so Q=0.04468/24.6=0.00182

 Contact persons: Robert Budny (budny@princeton.edu)

 Institution: PPPL

 Date of shot: 19901026

 Time of interest = 3.6 s

 Analysis codes: TRANSP

 Run number: 55851A47 done at PPPL, available via mdsplus

 Date of analysis: 20050414 TRANSP run by Robert Budny

 Assumptions for analysis:
   The time of interest of the shot is 3.6 sec. 
   The stored energy reaches a peak at this time, then rolls over 
   and decreases. There is no real stationary time during the beam 
   pulse; 3.6 sec was chosen because it is the peak of the stored energy.

   Flat Zeff profiles from VB are used in the analysis.

   ECE for Te(r,t), MIRI for ne(r,t), CHERS for Ti(r,t),
   Sawtooth analysis using sawteeth from ece
   Evolving boundary taken from magnetics
   NM1, NM2, NM3, and NM4 orifukes for H, D, trace T, and impurity thermal ions

   The TRANSP run simulated the measured neutron rate = 3.4E16/s, 15% 
   below measured
