Description
Experience at high luminosity hadrons collider experiments shows that tracking information enhances the trigger rejection capabilities while retaining high efficiency for interesting physics events. The design of a tracking based trigger for Super LHC (S-LHC), the already envisaged high luminosity upgrade of the LHC collider, is an extremely challenging task, and requires the identification of high-momentum particle tracks as a part of the Level 1 Trigger.
Simulation studies show that this can be achieved by correlating hits on two closely spaced silicon strip sensors. The progresses on the design and development of micro-strip stacked prototype modules and the performance of few prototype detectors will be presented. The prototypes have been built with the silicon sensors and electronics used to equip the present CMS Tracker.
Outcome of a simulation study of stacked modules performance will be presented. Preliminary results of a simulated tracker layout equipped with stacked modules are discussed in terms of Pt resolution and triggering capabilities.
The study of real prototypes in terms of signal over noise and tracking performance with cosmic rays and dedicated beam test experiment will also be shown.
