Jan 22, 2010\n\n This directory contains DIII-D eqdsks from and experiment performed\n March 4, 2008.\u00a0 This experiment had discharges which covered a range of\n plasma currents, toroidal fields and plasma triangularities.\u00a0 The following\n discharges were part of a four point current scan (0.5-1.5 MA) at a constant\n toroidal magnetic field (2.1T) and at a constant shape (average triangularity\n 0.55). These discharges were run at an approximately constant normalized\n toroidal beta (beta_n ~ 2.1-2.4). The pedestal temperature and density were\n not constant in the scan.\n\n The list of shots and currents for the eqdsks in this directory.\u00a0 These are\n the eqdsks that were used for the ONETWO analysis as part of the profiles.py\n analysis, used to generate beam pressure profiles in the analysis. The\n g-eqdsks are from: \/u\/groebner\/analysis\/exps\/2008\/theory_test\/python4.\n The a-eqdsks were obtained from mdsplus with the writea.pro IDL procedure.\n These eqdsks were earh run at the time of a specific Thomson laser pulse.\n The fitting model used for the eqdsks allows for a finite edge current,\n but the current density and pressure profiles should not be taken as anywhere\n close to the experimental values.\u00a0 These eqdsks were used for purposes of\n mapping experimental data on magnetic flux coordinates.\n\n shot #\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Ip (MA)\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 EFIT runid\u00a0\u00a0\u00a0\u00a0 EFIT time\n\n 132016\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 1.50\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 EFIT04\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 3023\n 132014\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 1.17\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 EFIT04\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 3023\n 132017\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 0.85\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 EFIT04\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 2998\n 132018\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 0.51\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 EFIT04\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 1948\n\n Results from this experiment have been discussed in\"\n\n Snyder et al., Phys of Plasmas 16 (2008) 056118\n Groebner et al., NF 49 (2009) 085037<\/span>\n<\/pre>\nThe discharges are analyzed with the TEQ equilibrium solver in the Caltrans code.
