Keerthi has reinstalled the SO2 source gas bottle onto MCIS. Presently it is closed off to the source. We have restarted the plasma. Present goal: a good setup for 33S5+ with background levels (hopefully near zero) on FC6. Source pressure was 4.xe-8 Torr this morning, and has crept up to 5.0e-8 since we restarted the RF.
Later... We scaled a A/q=5.5 tune up to A/q=6.6 (33/5). Separator field = 1459.9G. Tuning in progress.
Later... First pass, shown below. Skimmers < 5uA. Snap: 091013_1651.snapiosfc6
Source switched off for the night. |
