SL Plan

To lower the hydrogen fraction, we will start with LSN discharges, use 1120703020 to start, and maximize the RF power into discharges. We may switch to USN to stay out of H-mode and reduce RF faulting.

------------------------------
Physop Plan
------------------------------
Run high power ICRF to condition machine and reduce hydrogen, in anticipation of possible boronization Thursday evening.
Start from a shot similar to 1120703020 (1 MA, LSN), but with no LHCD, higher nl_04 target, and start ICRF at 0.6 seconds. We may then switch to upper single null, to stay out of H-mode, with an occasional shot in LSN to evaluate H/D evolution through the day.

*Tuesday (7/3) night through Wed (7/4) morning: 120 degree bake plus D2 ECDC.
Wed (7/4) mid-day through overnight to pre-run Thurs (7/5) morning: 60 degree C bake plus D2 ECDC.

The H/H+D rose for the first few discharges and reached 20% following
a 1 MA disruption on 009. The H/H+D decreased slightly and remained
at ~15% for the remainder of the day. We did some N2 puffing that
allowed higher power from FA-J antenna - reached 3.2 MW net power on
025.

The machine ran quite well today. We had some problems with runaways, including 1 runaway abort shutdown (shot 8), but no fizzles or duds. A leak opened at C-port during the day, giving high argon pressures in the machine (the secondary seal was purged with argon). Switching to pumping from purging resulted in nitrogen replacing the argon, so we went back to argon.

We switched back and forth through the day from LSN to USN, and got many joules of RF. H/(H+D) increased, then held steady, and may have been trending down by the end of the day. A number of the upper null shots showed signs of I-mode at high ICRF power.
