Display of cosmic ray event going through the pixel detector taken on October 18th 2008. Shown are the XY view (of SCT and pixels and of pixels alone) and an RZ view. The track has a hit in each of the layers in both the upper and the lower hemisphere. In the bottom of L0 there are even two hits due to a module overlap. Apart from the signal hits there is only one other hit in the pixel detector demonstrating the very low noise level in the detector. Photo #: cosmic3
