Agenda
- CDC Drawings
- Gas flow
- Upstream plenum seal
- End plate features
- Curtis' List from Last Week
- Donut and Feed-thru specifications GlueX-doc-1284 is a start on getting this going. We need to integrate this with the straw and endplate specifications so that all parts will fit together. Notes at the end of this indicate a scheme for doing this.
- CDC Assembly Procedures, GlueX-doc-1280 has been updated to include the stringing of wires. This impacts the design of the crimp pin. Namely, in order to be able to force the crimp pins into the plastic insert without damaging the wire that goes through it, we think that we need to have the lip on the crimp pin.
- Given the above lip on the crimp pin, we think that the crimp pin length should be roughly as follows (based on the pin diagram from Medelec).
- 1.7 mm long swaged tip
- 4.0 mm to start of press-fit shoulder
- 4.0 mm long press fit shoulder
- 4.0 mm long "crimp region" after the shoulder.
- Straw status. It appears that only one of Tim's questions with regard to the straws was answered in the email from Lumina (having to do with the Al layer). Can we get answers to the additional questions that Tim posed?
