As always, if you shared slides etc and haven't posted them yet, please do so before the next meeting for posterity's sake.

Our next meeting TPC Engineering meeting will be next week, at the usual coordinates: Wednesday, April 27, at 9:30AM Eastern:

Bob Azmoun will forward the direct laser attenuator PO to Glenn when he has it.

Bob et al. will continue to search for light yield work-arounds

Connor et al. will catalog possible features where we can buy some space in the TPC support to accommodate the TPOT

Connor will check in on the status of the rack panel layout with Joe. 

Connor will forward the TPC Support Structure Xometry quotes to Tom, so he can click 'purchase' when budget is stable (Tom just clicks buttons).

Connor will integrate FEE Cooling lines (1" diam) into the cable routing diagrams (away from TPC toward the recirculator)

Connor will keep the picture frame handy so it can be put on before cabling (Coordinate with Mike Lens) 

Connor will look at whether parts of the support structure can be trimmed to allow the TPC to install a little higher than current nominal.  Can the hanger get any closer to the TPC?

Connor will look for places where survey marks could be placed (to meet with survey folks before the end of July).

Connor will run the final design by Jin, then seek signatures on the strain relief design.

Connor will work on the gas line routing to the TPC WW.

Connor, Rich, and Chris will work on putting together an installation document (likely starting with the design review ppt) to help Chris P.  (This will also be part of the 'must have' documentation).  This will be priority once the parts orders are out.

Connor, Rich, and any others with Xometry or similar quotes for Support and Installation items will send pdf or similar copies of the quotes to Tom.

John C. will consider where we want to put accelerometers (and strain gauges) in order to monitor vibration of the TPC during transport and operation.  To be discussed late in the process (July?).

John H, Jim M, and others will think about what high-level documentation we want, and when it is needed.

Kristina will follow up with Tom/Keith about details of designing a flex cable.  Possibly a zoom conversation with Tom, Keith, Dan.

Rich will present the lift (using a strap on the open end of the tube and the front plate on the other side) when possible. 

Rich will purchase Duff Norton jacks fromGrainger. 

Rich will reach out to Alex Korel to see if we need to capture the sling on the open end in order for the lift to be 'safe'.  

Rob will keep us posted on gas rack news.

Ross et al. will figure out what the contamination issue is on the chicklets, and whether it affects the petals.

Takao and John H. will make a 'field trip' to Stony Brook Thursday, 4/7 to meet wtih Tom and talk about how to mate their side of the cabling to our side. 

Takao or John H. will give updates on the Slice Test.

Takao will follow up on the reworked cards that are now at BNL.

Takao will report back about first articles for the LV cable harnesses (3/9)

Tom et al. will test voltages for the HV cards once the x-ray box is ready.  Resistors will be purchased after this test (they are a negligible cost overall)

Tom will chat with James to talk about the order of priorities for TPC cart and other construction (weld, tapped holes, CM cutter, etc)

Tom will keep working on the paperwork for prefunding of the support and installation structures

Tom will let us know of any updates from Debrecen/spark detection.

Tom will try to identify any TPC engineering tasks that still need to be addressed.

Walter et al. will catalog possible features where they can buy some space in the TPOT to accommodate the TPC

When needed, someone should make the drawings from the models, get approval, and order...Connor says ~2 weeks required after we start the process.  May want to tie additional things onto the panels, so want to complete routing before purchase.
