QC6: Quantitative Test and Certification3
Ext. Barrel Module IFA030 - DAQ Run Number =1437
- DAMAGED FIBER: We have found some damaged fibers. Four fibers (cells D6 and D5) had a crack inside the fiber at the end glued into the aspirin tube . Another fiber (cell A16) had a little crack too. And we found two bad fibers (they gave us less signal) in cell B15 and B13. All af them were replaced using the teflon tube holes.
