FDC Weekly Meeting
Date: November 8, 2006
Participants: Daniel, Brian, Simon, Chuck, Tim
Next Meeting: Wednesday, November 15, 2006 @ 1:30 p.m.
Contents
Mechanical Drawings
Chuck and Tim presented first mechanical drawings of the FDC.
We went over what they did and made suggestions.
- We need to redo the preamp daughter board placement.
> 6 daughter boards per anode board (96 wires).
> 12 daughter boards per cathode board (192 cathodes).
> All daughter boards must be located with 120 deg arc.
- Work to reduce the number of bolt holes - need to set spacing
to be compatible with all +/-45 deg, +/-60 deg configurations.
- Design sealing cams for chamber through-bolts.
- Possible to use SS end-flange for compression to further reduce
chamber through holes?
- Chuck and Tim need O.D. and I.D. of the frame annulus. Need to
work with the board designer to finalize annulus size.
Cathode Board Update
Flex board manufacturer can make boards up to 60in wide. Brian is working to identify a kapton vendor. He will have word by Friday. - Brian expects that our flex boards for the mechanical mock-ups can be done by the end of the year. - DSC suggested to proceed with sandwich construction using kapton blanks. We will want to see how quickly the sandwich can be put together. - Dummy flex board design was completed by Jeff Wilson last week. Boards can be sent out as soon as kapton source is identified.
Full-Scale Tensioning System
Brian is nearly ready to contact the shop to have full-scale tensioning system constructed.
G10 Source
Brian has identified a G10 source and the frame construction can proceed once the design is completed.
Daughter Boards
Simon is looking into connectors for the daughter board. 5-mm spacing may be an issue. DSC instructed that he talk to Chris Cuevas.
Budget Work
Simon is working on improving our budget estimates for FDC construction. We will go over his work tomorrow.
Minutes prepared by Daniel. Send any comments or corrections along.
