Session leader plan for 1120905xxx: MP708 and MP682. This run is a continuation of run 1120904xxx. SL: R. Ochoukov (1120904xxx) and J. Terry (1120905xxx) PO: W. Rowan (1120904xxx) and S. Wukitch (1120905xxx) Critical diagnostics for this 1 1/2-day run are: emissive probes (A-B limiter, ASP, SSS) and GPI. XEUS and LoWEUS camera. CHROMEX (if available) GPI He puff is seeded with N2 to measure N2 penetration in presence of ICRF power. Step 1. Establish reference shot 1120904013 RF power as in 1120904013. Depending on the status of the D antenna, we will follow one of the two alternative routes for this run day. 1 good shot. Step 2. a) if D antenna is available then: repeat the ref. shot but vary the Z position of the plasma shot-by-shot or dynamically to poloidally "match" FA-J and D antenna "piercing" field lines. 3 good shots with FA-J and D antennas ramped simultaenously. 1 good shot with FA-J and D antennas ramped sequentially. Step 2. b) if D antenna is not available then: Repeat Step 1 but in an inner wall limited geometry. 1 good shot. Step 3. Repeat Step 1 but in an inner wall limited geometry with FA-J in monopole phasing. 1 good shot. Step 3. Repeat Step 1 but apply Ne seeding: ~2 psi from B-side lower, 150-200 ms pulse duration @ 50-60 V on the piezo). 2 good shots. Step 4. Repeat Step 3 but with FA-J in monopole phasing. 1 good shot. Step 5. Repeat Step 1 but with Bt = 2.725 T / Ip = 0.4 MA. Antennas powered sequentially. 1 good shot. Step 6. Repeat Step 5 but with FA-J in monopole phasing. 1 good shot. Step 7. Repeat Step 1 but with Bt = 8.0 T / Ip = 1.16 MA. Antennas powered sequentially. Will need a good 8.0 T reference shot, will consult with the phys op. 2 good shots. Step 8. Repeat Step 7 but with FA-J in monopole phasing. 1 good shot. Total number of shots is 11 with the shot sequence varying depending on the availability of the D antenna

SL summary for run 1120905xxx We completed the Ne seeding and the 8.0 T field shots. Key observations from today's experiment: 1) Ne seeding didn't make a difference on the induced plasma potentials in plasmas "heated" with FA-J in monopole. 2) ICRF-induced plasma potentials in plasmas heated with dipole FA-J antenna dropped slightly during Ne seeding, will need to examine more carefully what caused the drop and if there's any correlations with the Mo contents in the core. 3) ICRF-enhanced plasma potentials reached values >400 V in plasmas "heated" with monopole FA-J antenna @ 8.0 T. These potentials correlate well with RF-induced Er fields and radiative power losses from the core. Will have to do more analysis to compare with CHROMEX and ZEUS/LeWUS data on impurity contents in the core.

Summary The run was productive. The start up was quite robust with only one fizzle. Operation at 8 T had a rough start. I forgot to carry the BR_0 (-1 mT) and RCUR (3500) offsets from 012 and once they were set breakdown was robust. We had an IOC indication on 015 and fuses were replaced. Following a successful TF test under PLC control, we resumed 8 T operation. The 8 T discharges showed that the waves do not penetrate to the core (PCI) and there is little evidence heating (ECE). plasmas 18 fizzle 1 disrupted 2 cycle 1 TF test 1 --------------------- attempts 21
