OLIS is set up for 12C2+ delivery, with about 13enA on FC6 from the Supernanogan source presently. Beam was reasonably stable overnight, and should condition out better over time as well. Initial tuning into ISAC-I is planned to begin this morning.

A source switchover day was negotiated, with a goal to provide 12C2+ beam. As a practical matter, it's been an OLIS Maintenance Day, at least for the morning. Controls installed a cable to provide remote reset capability for the OLIS Enable interlock panel. However, it did not perform as expected first time, so Controls has elected to pursue this another time. Meanwhile, the remote cable is at the rear of the OLIS Enable panel, ready to be connected next time.

This morning, Keerthi started the Supernanogan, and established (evidence of) initial 12C2+ and 74Gen+ beams from it. Maintenance concluded around noon, and beam development resumed. Goals: Find clear 74Ge and 12C2+ peaks.

Beam used sporadically over the weekend. Note temperature response in beam. A power bump occurred at about 10:00, knocking out OLIS. It was challenging to come back to where it was before.

Source drifted overnight. Operators made a slight correction to silence an alarm. I have tweaked this up. Shown below are before and after. Marco believes present beam is unstable. I will see if I can tweak up the intensity, and perhaps that will satisfy all requirements.

Later... ~13:00 this is just about as good as it gets. Stripchart of the last couple of hours plus current excellent source parameters appended below.

Beam idle overnight. Source conditioned and changed a bit. Slight tweaking required to bring it back to stable.

A 16O1+ beam from the MWS is being used for SCC development and commissioning by agreement. Some sideshows getting there.

Later... At approximately 13:15, some event, a bias spark, it appears, took out a number of devices, most of which IOPS reset. The FUG blew a fuse on startup. Replacement OK. However, there remains an interlock light on the IOS:BIAS panel with no apparently unsatisfied interlocks showing. Controls is checking now (~15:00). Cause appeared to be an old version of a startup script on IOSIOC. The script has been updated so that this particular fault should not recur. Source restarted okay, but it took some doing to get the separator magnet back. It is still not optimized, but Marco can take it from here.

Source pulled down for Mg removal and cleanup. Done. Supernanogan refurbishing of MCIS optics complete, plus a comple of other items. Opened joints leackchecked and okay. MCISIOC was in a partial state, where devices worked but not interlocks. It turns out that Controls knows about this. Msg to investigate in the morning. Meanwhile, MWS is up with a 16O1+ beam on FC6 presently. FYI, the vacuum pumpdown curve during leakcheck and startup operations.

Photo-finish for TIGRESS this morning, apart from a cavity trip at around 6:00 a.m.. The MWS is running very well. Some EOB activities underway presently.

Plan for today: MWS pulldown for Mg removal and cleanup. If feasible, we will install the Supernanogan into the OLIS cage as well.

Beam was switched from 24Mg5+ to 26Mg6+ on Canada Day. Also, the source blinked out on Saturday. Remote restart okay. Source is running well.

Supernanogan maintenance continues. MCIS optics module was reassembled last week and installed this morning. Also a section of wveguide was replaced using a specially prepared section. TBD: MCIS:DB1 top place assembly, pump, then reinstall the cart into the cage if possible.

Later... solid target chamber installed with germanium powder, in preparation for an upcoming run. MCIS:DB1 is assembled. Volume is under high vacuum now. Leak detector also set up in preparation for checking tomorrow.

Delivery / standby continues.

Delivery to TIGRESS has begun. Beam from the source looks perfect. Looks like happy times for them. The plan is to eventually deliver 24Na5+ via the CSB. Maintenance Day for the radioactive lines is in progress now.

Later... This is about as good as it gets for magnesium beams from the MWS. Attached are screen shots of the source setup.

Delivery looks like it was pretty smooth over the weekend. TIGRESS expects to receive 24Na from ITW via the CSB this week. Yield goes today.

Tuning into ISAC-II was done yesterday, and continues today. The source was idle overnight. There were a couple of magnesium hiccups. Beam is looking fine right now.

Mass change yesterday morning from 26Mg1+ to 24Mg1+ from the MWS. It was tough to get stable beam from the source, and there are signs of Mg plating out on stuff. Keerthi was here last evening and again overnight to open the source and clean it up. Good job.

Later... There were a couple of power bumps over the lunch hour. One took out OLIS, the other didn't. Yes, the IOS Enable panel had to get a local reset yet again. I have an ECR submitted to Controls for UPS support on the 24V power supply that feeds it. Source restarted reasonably okay.

Beam was redirected to TIGRESS yesterday. RIB delivery to TIDA-II was rendered impossible due to a failure in the target or module. We have a verbal request in place now to change mass from 26Mg1+ to 24Mg1+. Attached is a plot of beam overnight on FC6 prior to changeover.

Beam waiting quietly on FC6. There was a power bump on Friday just after noon that tripped the world. Keerthi restarted OLIS. Beam never really came back to its former glory. We'll see if there might be an opportunity to touch it up.

Later... Mag stability program reset required. Internal field probe is at its limit. Hmmm... Meanwhile, revert to EPICS field probe, which unfortunately is not temperature-compensated.

TUDA-II began taking beam around midnight last night. Beam on FC6 for a good part of the night. Steady as she goes.

Beam idle overnight. Beam is being used as a pilot beam for this run. Source was knocked off by a power bump on Monday evening. Signs are that the root cause is the same as last time, loss of 24V to the IOS interlock panel.

On Saturday we opened the MWS and set it up for Mg operation. Everything went well. We are using the pair of half-moon Mg metal plates together with a thin Mg foil liner inside a bottomless quartz liner. Tune setup for HEBT/SEBT operation set up yesterday. 26Mg is selected. MCOL3A/B tuning for true centre is in progress right now while there is opportunity.

After EOB activities from 15N4+ run that ended this morning, we have begun preparations to switch over the ion sources. Turbos off just after 11:00. We have Mg source material ready. We will be using the MWS ion source. Due to the requirement to run the source at 53kV, we will also remove the Supernanogan cart from the cage as a sparking precaution.

Later... MWS backplate removed and reworked for Mg operation. Buttoned up and under high vacuum again now. Currently 2.5e-6 Torr at ~14:00.

Later... Plasma is lit. 24Mg begins to be visible after a while.

Note: Supernanogan cart is in its service dock.
