FDC Weekly Meeting
Date: October 25, 2006
Participants: Daniel, Brian
Next Meeting: Wednesday, November 1, 2006 @ 1:30 p.m.
1). We discussed the design issues associated with the tensioned
cathode planes. To eliminate pressure differential across the planes (to keep them flat), we will have to ensure the gas volume includes the regions between neighboring cathodes. The design will also have to include gas windows on both end of the each package.
2). We agreed to confine the electronics for each active plane to
a 120 deg arc to help with clearance issues. - Brian will make 3-D drawings at some point so that this can be studied.
3). We discussed the connections of the preamps to the wire planes and
cathode planes. We will not use a ``diving board" design, but will have preamp daughter boards that extend radially (against the circuit boards). This is important for stability. We can afford to take a few more cm of radial space. - Brian and DSC looked at the preamp dimensions and this looks like it will work.
4). We discussed the 120 cm O.D.. Nothing except cables should extend
into this area.
