Minutes
- Curtis reported on the status of the CDC construction.
- Layer 13 was completed last week and layer 14 is being installed this week. Layers 13-16 are axial layers, which are a little easier to install than the stereo layers. Installation is going smoothly.
- The weather has started to thaw a little in Pittsburgh, but we have not noticed any change in the particulate levels in our clean room. We remain around class 2000. We also have been trying to raise the humidity in the room. This has reduced somewhat the static charge, but humidity remains around 22%. We anticipate that this will start to rise as we warm up this week.
- CMU has purchased an automatic wire stripper to start start building the CDC wires to connect the chamber wires to the HVBs. A sample was shown at the meeting. We are waiting on an order of wire and we have been working on jigs to assemble 25 wires at one. The jig will also facilitate making very consistent solder balls on the ends of the wires.
- The plan is to fully produce the wires on the bench in 1/4-inch length increments from about 3 inches to about 5 inches. We believe that most will be in the 3.5 to 4.0 inch range. We will plan to color-code the length using colored heat-shrink tubing. This will also allow us to know the exact length of each hookup wire.
- As requested, a wiki-based log of the construction complications with the CDC has been started. It is linked from the CDC main page under the Construction Sub menu.
- Naomi received the re calibrated MKS units back yesterday. She hopes to put those back in today or tomorrow.
