Vertex Locator: impact parameter, vertex and proper time resolution Stephanie Hansmann-Menzemer 102 nd LHCC Meeting, 07.07.2010 10
Vertex Locator precision measurements at the IA point - Velo sensors all powered - cluster finding efficiency 99.8 % - Velo halves are open at begin of each run - fully closed at 7 TeV stable running sensor beam best single hit resolution ~ 4 µm Stephanie Hansmann-Menzemer 102 nd LHCC Meeting, 07.07.2010 11
