Paul Brendza reported

Today Q2 reached 1500 Amps.

We have spent the last several days trouble shooting the Q2 instrumentation and today all the pieces finally came together.

The Q2 coil is very well centered with the measured force increase at 1500 Amps only 3 KiloNewtons on top of 44 Kilo Newtons. This predicts an increase of about 30 KN at max current so support rod adjustment may be unnecessary. The max force limit set by SigmaPhi is 168 KN.

Everything else looks normal.

We still have more fine tuning of the controls to do but we are going home happy tonight.

We plan to advance the testing to 2000 Amps this week.

Next week we will be occupied with the arrival of the Q3 which is now in Newark NJ. We have to dismantle the Q3 yoke, receive the Q3, install and measure cryostat fiducials, install the Q3, re-assemble the yoke and align the Q3 to its yoke. Q2 testing cannot take place during these operations and we would like to have a SigmaPhi engineer here.

Q2 testing will resume on or about Dec 12th with the goal to complete prior to the Holiday shutdown.

The two dipole splices are complete as of about 5:30 PM today.

CTF

Normal

We are working with FM to resolve the parking issue in front of CTF.

Inlet solenoid valve actuator for K2 failed and was replaced.

HDR

Normal.

Techs noticed normal temperature fluctuation on cold box vacuum due to air cooled diffusion pump temperature sensitivity to outside temperatures.

2. Projects

UITF

Unknown priority

Pressure tests remain to be done on main transferline. The HDIce return line and electrical and controls work remain.

MSU

FRIB goal is to start compressors at the end of March. FRIB believes cold boxes will be ready near June July.

WFO is being negotiated.

2K cold box design is ready for RFP. Continuing work on ancillary equipment.

LCLS2

Bayonets will be shipped next week.

4.5K CB Directors Review. Schedule has been improved and pulled back.

3. Manpower

SLAC is moving Antonio from power to controls. They are assigning another SLAC engineer to oversee power interface work.

4. Info from Will

1. Watch spending on OPS and ENG accounts. Try to keep spending to critical "stop work" items.

2. We will likely be on continuing resolution for the full FY all the way until FY18

3. We will run up to the holidays but when we restart is up for debate

4. Other

Action Items

1. Must keep meeting to no more than 30 minutes

2. Finish appraisals
