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.

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 / standby continues.

Keerthi came in early this morning to set up OLIS for 24Mg delivery. HEBT tuning is in progress.

Beam on FC6 overnight and very stable. It grew overnight and continues to grow, but hasn't hit 1pnA yet. Marco is tuning with what he has. Let's see how it goes.

Meanwhile, the last Mg/MWS run occurred on October 27, 2010.

Trar chart of 26Mg on FC6 appended below. The natural abundances of 25Mg and 26Mg are similar.

Later... Marco reports no 25Mg at MEBT. See ISAC elog. Meanwhile, IOS mass scan of 24-26 appended.

Later... Play with source gases a little. Unexpected glitch: IOS vacuum is tanking... Settled at 1.2e-5 Torr. Checking... Looks like front collimator is plugged. Pretty good chance we were generating Mg beams. Meeting of minds... Consensus: Open and clean.

Later... Source opened and cleaned. Backplate and front collimator removed and serviced in the process. Pumping at ~16:15. Leak-up curve looks good.

Later... Source at high vac. Power on. Plasma lit like soft butter. Premature mass scan in progress. Done. MCOL3 restored to 5mm slit settings. Tiny beam on FC6. It can sit and grow overnight.

Hand it over to ICR at ~17:45.

Well, the plasma electrode shorted again, and Keerthi came in on Saturday to tear down the MWS and clean it. Beam is steady as she goes presently. Delivery continues today in lieu of RIB unavailability for today. A switch to RIB is expected this evening.

25Mg beam mostly sitting on FC6 now, as HERACLES takes RIB. Source was opened on Monday night to replace microwave window. Beam will be u sed again towards the end of the HERACLES run, then EOB tomorrow morning, Saturday.

Source opened, and aluminum components removed. Magnesium components from previous run cleaned and installed. Pumpdown in progress.

Later... Pumpdown looks wonderful. A couple of cycles with partial vent with N2 to help evaporate the methanol.

Later... Power is on. HV at 55kV for the night to condition. No plasma, no beam overnight.

Source conditioned nicely overnight at 55kV with a little RF power on. Source gases checked, final cage inspection. Ready to start.

Later... Source is lit. Let it grow.

Later... Lots of beam on FC3 but not a lot on FC6. Beam is broad. Hand it over to ICR for the night as-is.

Over the weekend, Keerthi had set up 22Ne4+ to FC6 for the purpose of developing a tune matched with a similar tune from the CSB. However, yesterday it turned out that the CSB could not generate a 22Ne beam sufficiently bright for tuning. So the project was scrapped. Keerthi then changed the source for 20Ne4+ operation, and handed it over to Marco yesterday. I think that is going well. Here is a trar plot of overnight beam.

MWS online. Note: A/q display is white. Possible culprit: IOSIOC. ICR will reboot it at first convenient opportunity.

Earlier, Supernanogan was set up with empty canister in preparation for Kr heavy ion run planned for this weekend. Canister and lines pumpdown in progress. However, a FR was issued for MCIS:BP1, which is losing ground pretty quickly. The two MCIS screenshots below were taken some five minutes apart. At this rate, there is no way the pump can bring the system to an operational pressure in time. For good measure, power-cycle BP1 now... it doesn't help.

MWS online. Beam sitting on FC6.

Mel returned two flow controllers today, borrowed in March and April.

MWS online. Separator magstab program offline. Check: Kepco is switched off and one lead is physically cut and taped over. That's pretty definitive.

Later... Keerthi has found that the EPICS probe has more diurnal variation than the separator power supply itself, so he disconnected it permanently. There is a USB issue with using our precision Hall probe that will require some expert Linux assistance to resolve.

EOB for SEBT1 run at 08:30, taking 11Li from ITE and 22Ne2+ from OLIS when needed. Attempted emittance scans last evening, but no data showed, and no more time to investigate. So be it. Another time.

Mid-morning the source was switched over from 16O1+ to 22Ne2+ operation for a new experiment. OLIS will be used as the pilot beam during this 11Li run to SEBT1/TUDA-II.

Beam was switched on Friday morning from 16O1+ to 22Ne2+. This time it's a pilot beam for a 11Li experiment.

Beam from MWS continues for pilot beam use into SEBT1. There are cyclotron issues with cryogenics, so 11Li delivery from ITE is suspended temporarily.

Later... we purchased a small UPS for the MCISRFIOC server. It arrived yesterday. After overnight charging, we installed it today. This is in response to the hardware failure a couple of weeks ago.

Beam on standby for pilot beam. Cyclotron is still down with vacuum troubles since ~03:00, so no RIB to ISAC.

Beam from MWS remains quietly sitting on FC6, on standby for pilot beam use to SEBT1. The cyclotron is still down with cryogenerator issues. Latest prediction is first protons this evening.

Supernanogan development, mainly for the sake of the upcoming 33S run, took place for a little while on Friday. It was expected to go through tomorrow (Tuesday), but we got the call for beam on Friday evening just before the Canucks game started. So it's up again. The beam was used for a while on Sunday to check beam energy.
