CDC
- Naomi showed plots demonstrating CDC gradually deteriorates its performance. The efficiency drops at big drift distances significantly; at the same time time-to-distance remains almost unchanged (Alex B.). The most probable explanation is gas contamination. It is strange that the hit efficiency exhibits 30deg phi variation. We discussed also other than gas explanations - some features in the tracking, electronics, etc. The plan is first to fix the gas leakage and than look with cosmics (also before fixing and disconnecting cables).
- Nacer finalized his studies of the dE/dx truncation. He simulated pions and protons and looked at
