The OPAL Silicon Microvertex Detector

Operating Results from 1993


Signal to Noise of Real Events
This Plot shows the Signal to Noise ratio for events taken in the 1993 run. Note that the S/N ratio on the Phi side is slightly higher than on the Z side.
D0 Resolution
This Plot shows the distance of closest approach of muon pairs from Z0 decays in the plane tranverse to the beam. In an ideal and perfect detector, this distance should be nil.
Z0 Resolution
This plot shows the difference in Z positions of the points of closest approach in the plane perpendicular to the beam. Ideally this should be nil also.
