Dear All,
The action items from the previous TPC Engineering meeting are below, and the status document is posted on indico as usual:
-- As always, if you shared slides etc and haven't posted them yet, please do so for posterity's sake.
See you all at the next meeting, at the usual coordinates: Wednesday, July 21, at 9:30AM Eastern:
Anyone, if you have a procurement, call it out! Tell Ross, Tom, and >>Ed<<
Bob and Ross will talk about aiming directed laser at CM stripes.
Bob will do vacuum (voltage?) test of QE of aluminum to confirm what laser power we need. Ross will clean up numbers on the number of clusters in a CM event vs a minbias event for Glenn.
Bob will talk with BS to find out the safe deadtime (propose 10us?)
Connor and Jim will meet before the next meeting to discuss the supports.
Connor has Dan's significantly stiffer original design, and will run through that modal analysis and show(?) that it doesn't change the natural frequencies enough to be attractive.
Connor will check in on the status of the rack panel layout with Joe.
Connor will consider how to safely remove the installation pipe. The concept of multiple support points looks promising, and more details are required. This will be the focus after the TPC support is finalized.
Connor will give clearance to the TPOT footprint as much as possible in the TPC design
Connor will integrate FEE Cooling lines (1" diam) into the cable routing diagrams (away from TPC toward the recirculator)
Connor will investigate the details of the picture frame connections (torque etc) for the FEA of the TPC support.
Connor will look for places where survey marks could be placed (to meet with survey folks before the end of July).
Connor will route RG59 cables, one to each HV card (one per module) plus additionally four more (inner field cage north, outer field cage north, inner field cage south outer field cage south) aka the three small wire feedthroughs. And will communicate with Tom and Joel to determine the full length of the HV cable.
Dan will keep in contact with nanomotion about the ceramics
Dan will send bob design of the lightpipe mechanical support to be propagated to vendors
Frank will estimate how long it takes to terminate cables and return that number to Tom.
John H. will reach out to Eric Mannel to add TPC to the overall grounding diagram.
Klaus will send HV information to Joel after his vacation.
Klaus, Nikhil, and Ross will continue to work with the evaporator to see if we can perform a controlled evaporation without letting up the chamber. We would like to calibrate thickness monitors and produce new chicklets for Bob.
Luke will finish up the modifications to the x-ray table design, reach out to BNL (Dan or Connor) when drawings in SBU vault are stable/done. (native inventor files send to Connor)
Nikhil will post the parts list for the evaporator support structure
Rob Pisani will produce a slide on the gas interlock/reporting requests for this meeting, and eventual propagation to Joel.
Rob will keep us posted on gas rack news.
Takao or John H. will give updates on the Slice Test.
Tom will let us know when HV cards arrive in first articles. (late July)
Tom will order the cards for the photodiodes.
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.
See you all at the next meeting, at the usual coordinates: Wednesday, July 21, at 9:30AM Eastern:
Have a good week.
