The feedback was done by adjusting the RF power. During the RI-Mode phase this leads in this shot to a serious reduction of the RF heating power, due to the dramatic increase of confinement when Ne seeding is applied. Two timepoints are included : one at t=1.4 (L-Mode with full auxiliary heating present) and one at 2.0s (RI-Mode point during Ne seeding, with full NB but reduced RF power) *Publication : not available *Additional information : 1D signals delivered in TXTR_68803_1d.dat : TXTR_68803.AMIN TXTR_68803.BT TXTR_68803.IBOOT TXTR_68803.IP TXTR_68803.LI TXTR_68803.NEL TXTR_68803.NMAIN0 TXTR_68803.PFLOSS TXTR_68803.PFUSION TXTR_68803.PHIA TXTR_68803.PICRH TXTR_68803.PNBI TXTR_68803.POHM TXTR_68803.PRAD TXTR_68803.Q95 TXTR_68803.RGEO TXTR_68803.TE0 TXTR_68803.THNT TXTR_68803.TI0 TXTR_68803.VSURF TXTR_68803.WTH TXTR_68803.WTOT TXTR_68803.ZEFF 2D signals delivered in TXTR_68803_2d.dat : TXTR_68803.BPOL TXTR_68803.CURNBI TXTR_68803.CURTOT TXTR_68803.DNER TXTR_68803.DWER TXTR_68803.DWIR TXTR_68803.GRHO1 TXTR_68803.GRHO2 TXTR_68803.NE TXTR_68803.NFAST TXTR_68803.NIMP TXTR_68803.NM1 TXTR_68803.NM2 TXTR_68803.NM3 TXTR_68803.QFUSE TXTR_68803.QFUSI TXTR_68803.QICRHE TXTR_68803.QICRHI TXTR_68803.QNBIE TXTR_68803.QNBII TXTR_68803.QOHM TXTR_68803.QPSI TXTR_68803.QRAD TXTR_68803.QWALLE TXTR_68803.QWALLI TXTR_68803.RMAJOR TXTR_68803.RMINOR TXTR_68803.SNBIE TXTR_68803.SNBII TXTR_68803.SURF TXTR_68803.SWALL TXTR_68803.TE TXTR_68803.TI TXTR_68803.TORQ TXTR_68803.UBPAR TXTR_68803.UBPRP TXTR_68803.VOLUME TXTR_68803.VROT
