FDC Weekly Meeting
Date: November 8, 2006
Participants: Daniel, Brian, Simon, Chuck, Tim
Next Meeting: Wednesday, November 15, 2006 @ 1:30 p.m.
1). 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.
2). 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 wnt 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.
3). Full-Scale Tensioning System:
Brian is nearly ready to contact the shop to have full-scale tensioning system constructed.
4). g10 Source:
Brian has identified g10 source and the frame construction can proceed once the design is completed.
5). 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.
6). 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.
