Experience at high luminosity hadron collider experiments shows that tracking information enhances the trigger rejection capabilities while retaining high efficiency for interesting physics events [1]. The design of a tracking based trigger for Super LHC (S-LHC), the high luminosity upgrade of the LHC collider [2], is an extremely challenging task requiring the identification of high-momentum tracks as a part of the Level 1 trigger decision. Simulation studies show that this can be achieved by correlating hits on two closely spaced silicon strip sensors. This paper focuses on the design and development of micro-strip stacked prototype modules and their performance.

Abstract
Experience at high luminosity hadron collider experiments shows that tracking information enhances the trigger rejection capabilities while retaining high efficiency for interesting physics events [1]. The design of a tracking based trigger for Super LHC (S-LHC), the high luminosity upgrade of the LHC collider [2], is an extremely challenging task requiring the identification of high-momentum tracks as a part of the Level 1 trigger decision. Simulation studies show that this can be achieved by correlating hits on two closely spaced silicon strip sensors. This paper focuses on the design and development of micro-strip stacked prototype modules and their performance. The prototypes have been built with the silicon sensors and electronics used to equip the present CMS Tracker [3]. Correlation of signals collected from sensors are processed off detector. Preliminary results in terms of signal over noise and tracking performance with cosmic rays will be also shown.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
