MCIS configured for 33S+6 yesterday afternoon. Beam grew nicely overnight. Beam development expected after source hand-off.

Delivery since Friday Beam on but intensity is dropping, suggesting that enriched 33S powder is running out. Plan in place to add more this evening.

Beam petered out earlier this morning after an attempt to tweak the RF frequency. Restored. Plasma was on throughout. ICR has lowered RF amplitude to match beam intensity to yesterday's running conditions.

Delivery continued uneventfully overnight and is continuing.

Later... source is just getting better and better. See Stripchart below.

Delivery continued overnight.

Deliver concluded yesterday morning around 09:00. Pity to have to switch off the source. OLIS is now in its Shutdown.

Two weeks of OLIS Shutdown have begun. The plan is to complete refurbishing this week and pump next week, with 36Ar+6 beam ready at the end of it. IOS is vented and open. The Supernanogan cart is out, vented and open. Plasma chamber cleaning and refurbishing in situ are in progress. The IOS upstream optics DB1-3 have been removed for refurbishing on the bench.

Later... Supernanogan MRO completed and closed. Pumping underway by ~15:30. Leakup curve appended below.

MCIS pumped overnight. Still coming down.

MCIS pumpdown continues well. IOS optics coming along. DB3 installed last night and IOS is under vacuum very early. DB1/2 optics will remain out until the end of the next-up MCIS run.

MCIS pumped well overnight. Source development imminent.

Later... possible IOS intervention. Spin down turbos in anticipation... Meanwhile, MCIS pressure was at 7.8e-8 Tott at the start, and dropped to 7.4e-8 Torr immediately upon closure of MCIS:IV1. Note that IOS:IV0 remains open with interlocks bypassed.

MCIS continues to pump well. IOS DB assembly planned for today.

Later... DB assembly complete and IOS under vacuum. Present pressure: 1e-6 Torr at ~18:00. All optics hold voltage.

IOS pumped well over the weekend. Present pressure is 1.5e-7. MCIS pumps off for setup.

Later... Supernanogan is online with better than 250enA of 36Ar7+ on FC6 presently ~17:00. Note: MCIS:TP3 is off by intention for this run.

Supernanogan is online with 36Ar+7 on FC6 overnight. Looks good. Note: The source gas arrangement (enriched 36Ar) utilizes double buffer canisters and calibrated leaks, and requires MCIS:TP3 off.

Controls is preparing to perform an IOSIOS reboot for the sake of new code for ILT:RPM8 or something like that.

Supernanogan 36Ar+7 source development in progress. RF frequency scans are the agenda for today.

Later... Some good beam results and 300enA beam on FC6. Note: 5mm slits are in.

Supernanogan on overnight with 36Ar+7 on FC6. Nice.

Today is the last day of scheduled OLIS Shutdown. Expect more source development today followed by a hand-off to ICR at some point.

This entry was incorrectly added to the OLIS logbook.  it has been moved to the I3 logbook.

MCIS-

the cart was moved into the HV cage.  The facilities will be connected and an oven will be tested for the upcoming Se experiment.

Will take measurements for installation of key interlocks on cart power supplies.

SIS-

the filament assembly was removed for inspection.  When increasing the ionizer current it would work correctly until about 20 amps.  Then the current would stop (like an open cct).

MWS-

will prepare for Be later this week.

The remaining connections were done on the MCIS. 

A piece of 1/8" teflon was installed between the back of the sputtering tube/motor and the HV cage.

Ray confirmed the cart power supplies (heater and sputtering) Epics page readouts for Voltage and Current are okay.  The Heater p/s was left plugged into the cart receptacle.  The Sputtering p/s's are unplugged.

The MCIS:FC0 OUT limit was not actuating.  It was adjusted.

Keerthi tested the oven last night and was getting Se (14/10/24 it appeared to be Se, but the Prague magnet was not working.  Further investigation revealed it was not).  The oven supply is currently bypassed and ON.

Evigeny is working on the Alga and CPI amplifiers.  Both signal generators and the amplifiers are powered ON and connected.  Alga to the dummy load and CPI to the MCIS.

The ALGA amplifier and its signal generator have been turned off at the request of Controls.  They have had communication issues and are looking for any recent changes.

The nitrogen bottle needs to be replaced.

MCIS-

Does not appear to be producing very much Se.  There is a lot of calcium and potassium.

Cart is removed.  Unplugged CPI amplifier.   No extra time for investigation.  Set-up required for MWS.

note:  one cart wheel is damaged.  will need to service, or replace in s/d.  other wheels will need to be check as well.

MWS-

Changed to Be plasma electrode for upcoming experiment.
