Detector updates
- CDC has been successfully fixed after the "near-miss" event. The card that Nick suspected for noise was tested with a scope and was OK. Fernando: "the electronics saved the day" (i.e. the detector).
- Vlad reported on the FDC gain calibration. He did this before, but now the cathode resolution was improved and he uses now higher statistics (~1M hits per chamber). In the attached plots we see the distribution of the gain coefficients is getting narrower with each iteration - 4 in total. Some channels tend not to be calibrated producing tails in the distributions. Vlad will also work on parallelizing the calculations: separate job for each chamber.
- Lubomir proposed
