- Lubomir included in the Fast Track file, the production of the one-layer prototype which will take 2.5 weeks if having 8 technicians. This includes one wire and two cathode layers. Suppose we start on Oct.4 we will be ready with the prototype on Oct.20. Then, we can start with the mass production at the beginning of November. This answers Fernando's questions when we will need the PCBs. Fernando also asked if we have the 8 technicians needed for the job. Eugene answered, we would have to hire new techs. It will be difficult because the term will be only for one year, but probably we will need some of them for the constructions in the hall. This will be synchronized later when it will be clear when we will have the clean room. | - Lubomir included in the Fast Track file, the production of the one-layer prototype which will take 2.5 weeks if having 8 technicians.

| − | - | + | - No news from Bill about the design of the wire stringing fixtures. He wanted to use the strongbacks that are at IUCF: Lubomir tried to contact Keith Solberg from IUCF, without success so far. In this line, the system for wire position measurements was recovered at UVA, they are testing it right now at UVA. We will have to find a way to bring it here. |
They plan also to improve their system for tension measurements, based on exciting the wires by induction from an electrode and looking for the resonance frequency. Glenn suggested to talk to Mac Mestayer from Hall B about their system. Fernando said that the problem with the Hall B system is that you need to make connections to both ends of the wire. In our case this will be difficult especially for the field wires. | They plan also to improve their system for tension measurements, based on exciting the wires by induction from an electrode and looking for the resonance frequency.

| − | - Roger | + | - Cathode foils: Roger showed us a plastic cylinder and a paper sample he recived from the company to be used for transporting the foils. Mark said this paper should work (he had bad experience before with a sticky on one side paper). Fernando and Glenn suggested possible improvements: placing caps on the cylinder ends, using two cylinders with the foil in between. Roger will further communicate with the company to improve the packaging. |
- Roger is ready with the design, except for a few cosmetic changes. He will send the Gerber files to the company by tomorrow and expects estimations | - Roger is ready with the design, except for a few cosmetic changes.
