Minutes
Participants: Curtis (CMU), Sean (NU), Eugene, Luke, Dave, Chris, Nick, Simon, Beni, Fernando, and Lubomir (JLab).
CDC analysis update
- Simon showed new alignment results and compared them to the results for the fall 2014 run. For the new alignment he used external (BCAL) tracking, for the old - tracking from the CDC itself. One can see that in the new results the offsets are smaller - few hundreds microns, while in the old results we there are groups of straws with offsets of ~600 microns.
- Curtis has seen recent results from Mike using Millepede package: the offsets are randomly distributed, not in groups as it is in the Simon's results. Will discuss this when Mike is back.
FDC update
- Lubomir looked at the ratio of the charge on the upper and down cathodes from the last run data.
