Current total loose wires we need to fix (try pulling on the pin) on both chambers combined (our only uncertainty in how many additional replacements there could be):

Current total known replacement wires that need to be done:

S2: 17 wires; 6 field, 11 sense SL1 - 6 field, 9 sense SL2 - 2 sense

S3: 16 wires; 14 field, 2 sense SL1 - 10 field, 1 sense SL2 - 4 field, 1 sense

Total wires left to replace between both chambers: 33

S2 is aligned for stringing on SL2 - 2 wires left to string on this superlayer before we need to re-align. S3 is aligned for stringing on SL1 - 11 wires left to string on this superlayer before we need to re-align.

Expect to finish restringing the above 33 wires in 2-3 weeks.

Thursday (5pm -> 7pm), Friday (8:30 am -> 4pm), Saturday (9am->4pm)

Current total known replacement wires that need to be done:

S2: 17 wires; 6 field, 11 sense SL1 - 6 field, 9 sense SL2 - 2 sense (done)

S3: 16 wires; 14 field, 2 sense SL1 - 10 field, 1 sense (found broken sense) SL2 - 4 field, 1 sense

Prepare to Ship 2 chambers

S6 is boxed up and ready to go on a pallet

S5: Pictures taken on most sense wires, SL1 has almost 3 Ua of current draw (need to debug), need to box it up unless we ship S1.

Ship back equipment: ship one of the A-Frames and associated equipment for stringing one chamber.

Measure Sense wire tensions as a function of Sector position

How do the sense wire tensions change with sector position (i.e. gravity)?
