| − | - Dave: wire frame # | + | - Dave: wire frame #6 is out of the stringing table and now working on #7: it was strung yesterday by Casey and Al in ~4 hours (record). Then the wires were taped and now doing position measurements. Aanatoly finished replacing the caps on frame #7. Cathodes: Tina and Mike tensioned type-1 cathode from set#7 and put the daughter cards on type-2 from set#6. Anatoly finished testing all the 80 foil sets. Wire frame #6 will be populated by Chris tomorrow and then (possibly on Monday) the central wires will be deadened. |
| − | - | + | - In the construction tracking at the second page there's table about the wire frames explaining differences in the material/procedures used: Epon or Epo-lite, with or without Humi-seal, capacitors replaced/not replaced, and whether the wires were deadened. Starting from frame #6 and up (6 is the consecutive number, not the frame number that is labeled) on all the frames the caps were/will be replaced without Humi-seal and Epon was/will be used instead of Epo-lite. If we exclude the first four wire planes as spares, there's only one (#5) production frame on which the caps were not replaced, but still Epon was used. We discussed if we want to replace the caps on all the frames and how, or if we just want to build new wire frames using the latest technology. Bill: we need to replace the old caps everywhere. However it will be very difficult, time consuming and risky: one easily damage wires especially on the frames with Humi-seal on the caps. |
| − | + | Eugene: it might be better just to make new wire frames, but it has to be evaluated. Lubomir will collect more information for the next meeting what needs to be purchased to produce extra wire frames. | |

- We will spend some time tomorrow preparing for the hurricane. The main problem we expect is the lack of electricity. Therefore, no gluing will be done tomorrow. Bill suggested to cover all the frames that are outside with vacuum bagging material. | - We will spend some time tomorrow preparing for the hurricane.
