Hardware Minutes

Participants: Curtis, Naomi, Beni, Simon, Lubomir, Elton, Dave

1. FDC Update
2. CDC Update
   1. Wire stringing has been completed and the chamber lowered to horizontal.
   2. We are expecting the survey team from JLab next week, the plan is to survey the 200 holes which were surveyed previously with a Faro arm.
   3. The resistance of the wires will be measured after the surveying.
   4. We are planning to use Al standoffs in place of the brass ones because their resistance is similar and Al is so much lighter.
   5. Calibration with cosmics is undergoing discussion. We have been thinking about possibilities for calibration with scintillator paddles above and below the magnet.
   6. We are starting to work on the TDR.
