Minutes
Participants: Fernando, Casey, Roger, Brian, Glenn, Bill, Kim, Simon, Beni, Eugene, Lubomir
Production space
- Tim is the contact person from our side for the 727 B.C. property. He will meet with Rusty to discuss our requirements and all the details. There was a meeting with the network people from the computer center. They will organize the network using their equipment. We will pay for the COX business connection.
- A document has been created (attached above) with the intention to list all the steps of the FDC production and describe them in terms of manpower and time. Lubomir will seek help from Brian and Mark to estimate the manpower required for each step. The wire stringing procedure will be based on the UVA experience. Then Bill will review the document and we will continue with creating a flowchart of the production.
Electronics
- PCBs: some minor modifications have been done and the design is now final. Kim got quotes from San Francisco Circuits ($76K) and CEM ($41K) for 28 of each board. Both are bellow our budget ($98K). CEM has special notes: quotation based on using FR4 instead of G10 material (not acceptable!) and that the flatness specs may not be achievable. Bill, Brian and Fernando discussed what is our actual flatness requirement. Kim expects one more quotation.
Cathode redesign
- Roger discussed the plots attached above. Everybody agreed on the design of the beam hole (first plot). had several questions related to the ground of the cathode daughter board (flex) design, and also the strip labels.
