JET_53550_com.dat = comments file for ITPA WDB Profile Database submission Tokamak: JET Pulse number: 53550 Shot description,purpose of the shot: ELMy with Ar gas injection, low triangularity Contact persons: Robert Budny (budny@princeton.edu), Jef Ongena, Xavier Garbet Institution: EFDA-JET Date of shot: 20010209 Time of interest = 21.0s (61.0s in JET PPF time) for steady state Analysis codes: TRANSP and EFIT (for plasma boundary) Run number: 53550C03 at PPPL, available via mdsplus Date of analysis: 20080319 TRANSP run by Robert Budny Resubmission fixing QICRHE and QICHRI Assumptions made for analysis: Ti, toroidal rotation velocity, and Zeff profiles from CX measurements. Te and Ne profiles vs. radius from LIDAR measurements. The radiation emission profile was derived from inverting two bolometry views. Particle confinement time is calculated from source rates. q profile calculated in TRANSP from poloidal field diffusion. Additional information: Pulse #53550 was an ELMy RI mode shot with Ar inj. The Ti, rotation, and Zeff profiles were measured from 16.2 to 24.5s between R=3.24 and 3.80m. The direction of the toroidal field and plasma current were in the normal JET direction - clockwise viewed from above. The NBI voltages were 135 keV for 7 beams, and 80keV for 8 All beam related quantities (energy, particle sources, currents etc) have been smoothed to suppress Monte-Carlo noise. In the 2d file the deuterium and trace T densities are stored in NM1. NM3 contains the combined Be, C, and Ar impurities. 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 - min(R(zmin),R(Zmax)))/a XPLIM and SEPLIM are given by EFIT. The TRANSP run gives a simulated W_dia 15% above the measured value and a neutron emission rate 10% below measured.
