1. FDC Update
2. CDC Update
   1. Construction Update
      1. Jim (JLab) has nearly completed his survey of the CDC.
      2. The cheeseplate has been much improved by sanding and buffing. When the buffing has finished it will be cleaned.
      3. The rohacell ring arrived, looks good, we will dry-fit it.
      4. The thermocouple kit has been ordered. We did not order a control unit for it - we are leaving this to Elliott. We plan to attach 10 thermocouples to the CDC, 5 inside each gas plenum and passing through the plenum wall to the outside, and some shielded thermocouple extension cables to run from downstream to upstream endplates. More extension cables will run from the upstream endplate to the electronics racks.
      5. Naomi is still working on timing.
      6. Tim asked us to think about how to check that the gas is filling all areas of the CDC before wiring it up.
   2. Cosmic calibration
      1. Simon started working on some straight track fitting software with electrons to see if he could move the wires and then correct their position.
3. TDR Update
   1. The CDC team have looked at this but no real progress yet.
