High-Resolution Tracking Tools for the CMS Pixel Detector Upgrade

With the impressive performance of the LHC delivering two times the design luminosity an upgrade of the CMS Pixel Detector is required to maintain and extend the tracking efficiency. The upgrade plans comprise several changes in geometry and material budget as well as a new Readout Chip (ROC). This ROC is being tested at various institutes in the laboratory and in test beams at DESY, CERN and FNAL. In the DESY electron/positron test beam, the DATURA high-resolution beam telescope is used to explore the features of the new chip design. The DATURA Telescope features six MIMOSA26 MAPS planes with an intrinsic resolution of 18.4um, crossed scintillators as four-fold coincidence trigger and movable mechanics with adjustable plane distances and cooling. This poster presents the approach to high-precision tracking using the DATURA telescope with CMS Pixel ROCs as Device Under Test (DUT) and shows results from test beams of the past months
