We have a change of schedule. Due to circumstances, Sophia will continue tuning to TIGRESS this morning. Sgan Development will resume this afternoon.
Details: The beam path through the TIGRESS chamber is clear presently, and no detectors are mounted. It is the perfect time to send a nA pilot beam to the end of the line. TIGRESS intends to install electronics starting at noon. Sophia expects to have tuning comfortably completed by then also. She and I have agreed to the following schedule:

Note: An SC vacuum issue arose this morning, which truncated Sophia's tuning efforts for today. We have agreed to a slightly earlier handover time on Friday, so that she can tune through the chamber. It will be more difficult, as there will be detectors installed by then.
Beam has been on FC6 for an hour or so. It looks pretty good. Stripchart attached. Save: 090714_1231.snapmcissebt3a. Note: There is something fishy about the slit panels. I think an IOC got rebooted somewhere along the line, and the slit motors are out of calibration. I have recorded the pot values in the save file. Emittance scan of Sopohia's 18O4+ beam appended. |
