FDC Weekly Meeting
Date: November 22, 2006
Participants: Daniel, Brian, Simon, Tim, Chuck
Next Meeting: Wednesday, November 29, 2006 @ 1:30 p.m.
Tim and Chuck have not made any additional progress on the FDC mechanical drawings as they have been working on drawings for the entire GlueX detector system.
Cable Support System
- We discussed the cable support system and how the FDC system will be installed within the solenoid. The issues include the downstream end of the BCAL with the Winston cones, SiPMs, and cables. We cannot be in contact with any of this. Also the FDC system will be assembled onto a special cart and will engage with the fixed rails within the solenoid. The FDC system will then slide into place as a single unit.
- The FDC system should be able to be connected to power and readout on the installation cart and then slide into GlueX. Tim and Chuck will begin to work on the design.
We discussed issues with preamp cooling - water vs. dry air. More details are needed from Mitch Newcomer regarding the ASICs before we can proceed. DSC will follow up on this.
- We discussed how to power the ASICs with a common input line (or lines) so that we don't have to make connections separately to each daughter board. - We need to discuss this with Roger and Kim at our next meeting.
- We reviewed the FDC budget - Brian was brought up to date on the numbers that he should help to provide. The accuracy level is 30% for our purposes. - The budget is due to Elton and Curtis by Dec. 19.
Dummy Cathode Design
Roger has completed work on the dummy cathode plane. Due to the $20k cost, we need Elton to sign off on this.
Minutes prepared by Daniel. Send any comments or corrections along.
