High Voltage cage is on at ~17:43pm

Interlock cleard and HV (10kV) is on at 17:53pm

Source is now pumping down. Damien, Please start the source as soon as you arive. Try to keep PE current below 500mA. Optimum is ~200mA

Source started at 800W of microwave power and 2cc/min neon gas easily. New magnetron produces more power than the old one.

We should try to keep MW power under 500W during running and use only 800W for ignition.  EE left off for the night.

Removed titanium from the back plate and clean the source.

But left the PE titanium insert since Bob and Marco badly want the 12C++ beam from the source fast.

Background 12C++ was only 400pA so installed a small canister with CO in it with bellow atm. pressure.

Now source is running with ~2nA current.

MCIS finished xenon development. MCIS is off and isolation valve is shut.
A new oxygen gas line is installed to microwave ion source via a hand valve neat PE.
Hand valve is tuned as a small leak so that the plasma can run with all other gas valves are shut.
However if one need to start the source Ne gas valves are needed to be opened.
A 3.13nA of 16O+2 is sitting at FC6 and ready to use as pilot beam.

During the last week we delivered 18O+2 from microwave ion source to Ritu.

Over the week end changed to 40Ar+2.

Ritu informed us 18OH2 is coming with 40Ar+2.

Moving the slits ops managed to reduce 18H2 contaminant from the beam.

Good lesson for the future. Bad combination one after the other.

IRIS beam delivery is completed with extra 3 days of beam providing to them.

18O2 and 40Ar+2 were delivered with few attenuators i place.

Controls group may need some assistance from OLIS group in order to trouble shoot the problem.

IOS mass scan does not work.

Elog is now functioning. We can start entering notes

Chris confirmed the first SIS beam would be Na+1. Next Rb+1 and then Li+1

We did a test yesterday with the new Alga Microwave RF AMP, model # ALPA 50 Watt, serial # 130684 to be used for the MCIS.  We used the RF Generator from MISTIC and set the frequency to 13.80 Ghz, note that the RF Generator was/is  limited to 16DB maxiumum RF output.

The RF cable that we used was from the 200W RF AMP, it has a 20DB SMA attenuator at the Generator end, so we could only get about 25 Watts maximum output.
