- 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 regarding details of the attempts to find another source. Ross Small from the procurement states that "at this point approval of a sole source is not a sure thing" and he suggested advertising it in the FedBizOps site for 21 days. We discussed what are the pros and cons of such advertising. Pros: no longer sole source and it takes only 21 days. Cons: if some vendors decide to bid they have to prove they can do it and go through the same stages (first article production) as with allflex which will take a lot of time.

- Some of the fixtures for the wire stringing wre made in the machine shop. Tomorrow they will drill holes in the granite table in 126, that will be used for stringing. Starting next week Bill will have more time to work the stringing. David brought the position measurement system from UVA on Friday 08/27. It turned out the motion carriage doesn't have enough travel to cover our chamber (970mm). Last week David disassembled the carriage with the stepper motor and the control from the FNAL wire winding machine and got it working with a very old computer! Bill prefers to use a system that works

Last week David disassembled the carriage with the stepper motor and the control from the FNAL wire winding machine and got it working with a very old computer! Bill prefers to have a ready system (stepper motor with the control and the software) that works with the new computers. Beni has a small power stepper motor and we will see if we can use it. Bill wanted to know
