- There will be two conference calls with two clean room vendors today. Bill will participate. There was a list of questions submitted to the vendors with regard to reducing the cost. Pictures of the Blue Crab property as of yesterday 08/25/10, are linked above. The accelerator people have stored there some stuff temporary.

- The price of the clean room came high after the second bidding (~$300K), but we got green light from our bosses and we hope there will be no other showstoppers. We discussed what we can do in advance without the clean room: Rohacell gluing, Rohacell lamination. We may be able to store the Rohacell rings in the office space of Blue Crab. There's now more space in Blue Crab (the magnet stands are not there) so we may start moving some stuff there (like tables) whenever we have time for that.

- A budget of the FDC production (linked above) was prepared based on the Fast Track labor estimates done by Bill and Lubomir and the equipment and material list from David. This estimate does not include the electronics, gas system, support frame and is only for the work related to the production at Blue Crab. We have about $1M in the baseline for these activities (both materials and labor), but need about $1.43M for the production; so the difference is $430k in addition to the $360k that were overspent already for the FDC project. Beni asked what was underestimated in the project. Eugene: mostly the labor costs. Bill mention that some additional procurements (like for the end caps) have to be included in the budget. As soon as we have a realistic estimate for the FDC budget, Eugene suggested to formulate a change request with items indicating the number of the layers that will be produced on month by month bases.

- Christopher has created a logbook with information about the PCB tests for each board. David suggested implementing the traveler system: a data base with some parameters for each part or operation done at a certain time. He's working on the list of the parameters and needs input from everybody.
+
- Fernando prepared two pre-amps in discriminator mode, together with the cables and ECL translator. Beni is testing them. Fernando wants us to answer in one week whether they are acceptable. There's some delay with the delivery of the PCBs. They had to be here on Monday, but will have them next week. The contract for the PCB stuffing is ready submitted to the procurement. Will have the first 2x6 PCBs (1st article) within two weeks and after the approval the rest (26x6) will be done in 4 weeks. We discussed how we will store the PCBs: in boxes, wrapped and taped. Fernando is also working on the procurement of the HV mini cables.

- Cathode foils: Roger communicated with Advanced Circuits and expects today an estimate. Then he will return to the procurement the forms and the information they requested. If Advanced Circuits can provide an offer, then it will no longer be a sole source procurement. If not, it will be used as an argument for the sole source procurement.
+
- Cathode foils: Roger got an answer from Advanced Circuits that they can't produce the cathode foils because of the big sizes. Roger is still waiting for an independent estimate from them. He submitted to the procurement answers of a second set of questions from them
  
 
- A Rohacell ring was glued to test the procedure and the new templates and will be used for the first new design prototype. It will be laminated to the first article g10 ring (Bill expects it at the beginning of October, maybe earlier). Then we will laminate the PCBs (first article).
