MP330 Localization of the effect of Boronization Session leader: Wukitch Physics operator: Rowan Overnight ECDC in D2, and bake at 60 C. Run begins at 09:00 and ends at 17:00 Power systems as on 1060613039 (1.0 MA fiducial, 5.4 T, LSN) A-coil configuration: normal [+Dtop -Dbot -Jtop +Jbot] and enabled. Gas Setup: fill B-Top with 6 psi D2 Hybrid enabled (PG4) fill B-side lower with 1 psi Ar + 2 psi Ne Hybrid DISABLED (PG1) fill B-side upper with 15 psi 3He Hybrid enabled fill B-main (C-side) with 40 psi D2 Hybrid enabled (PG3) fill NINJA with 12 psi D2 Enabled ** 3He 100 msec puff at 0.2 sec *** Boronization system set up for between-shot boronization before the run but do not open the diborane bottle. *** All between shot boronizations (BSB) 10 minutes. Each sweep 200 seconds with a 20 second pause. All sweeps are 65-75 cm with pause at 70 cm. Boronization pressure set to 5 mTorr. Enable the following gate valves and shutters, assuming no vacuum problems: ECE, VUV, Z-bolo shutters; these must be disabled for between-shot boronization The A-Side TV camera shutter must be CLOSED before the boronizations (before the run and for the rest of the day). The MSE shutter must be CLOSED before the start of the run, and remain closed throughout the day. Important Diagnostics: standard impurity spectroscopy, Mo source monitor, McPherson, emissive probe ------------------------------------------------------------------------------- ICRF Setup: FMIT#1,2,3&4 in run-on by 8:30. ------------------------------------------------------------------------------- Plan: use 1 MA, 5.1 T, nl_04~1 A) No boronization comparison: 1060613039 LSN - 2-3 shots with J, D/E at different times. B) Boronization erosion dependence on antenna (8 shots + 4 BSB's) 1) BSB followed by a D/E heating shot 2) J heating shot 3) BSB followed by J heating shot 4) D/E heating shot 5) BSB followed by two D/E heated discharges 6) BSB followed by two J heated discharges may repeat 1-4 depending upon results C) use -90 and +90 and repeat B1-4 D) (5 shots) Upper single null plasma, H-mode power threshold comparison.

| Run Summary:
Despite an abbreviated run, we started the boronization erosion study comparing D(H) (D+E antennas) versus D(3He). The overall plasma performance was not reaching the 145 kJ we obtained in the April run at 5.4 T but we obtained reasonable comparison for two post boronization sequences. Surprisingly, the D(3He) was not particularly worse (difference was <10% and there was some indication that) than D(H) with respect to boronization erosion. There are some observations that D(3He) has a stronger edge interaction: D-alpha increases significantly and the Prad is higher in L-mode. |
