tftr_80539_com.dat = comments file for ITPA WDB Profile Database submission Tokamak: TFTR Pulse number: 80539 Shot description, purpose of the shot: D-T supershot achieving the TFTR record DT fusion power (10.3MW) with 25.0 MW T-NBI, 14.6 MW D-NBI and Q_DT=0.26 Contact persons: Robert Budny (budny@princeton.edu) Institution: PPPL Date of shot: 19941102 Time of interest = 3.76 s before a minor disruption (standard kink -> ballooning), followed by carbon bloom and increase in n_e Analysis codes: TRANSP Run number: 80539A26 done at PPPL, available via mdsplus Date of analysis: 20051107 by Robert Budny Assumptions for analysis: 80 zones, ESC for the equilibrium ECE for Te(r,t), MIRI for ne(r,t), CHERS for Ti(r,t), Carbon density profiles used for Zeff profile; good only during NBI phase Sawtooth analysis using sawteeth from ece Evolving boundary from magnetics NM1, NM2, NM3, NM4 files for H, D, T, and impurity thermal ions Additional information: the high performance (fusion yield) resulted from extensive wall conditioning to lower the wall fueling. The neutron emission rate was simulated accurately by TRANSP.
