Test beam results of the first CMS double-sided strip module prototypes using the CBC2 read-out chip — •Ali Harb, Johannes Hauk, and Andreas Mussgiller — DESY-Hamburg

The CMS Binary Chip 2 (CBC2) is a prototype version of the front-end readout ASIC to be used in the silicon stripmodules of the CMS outer tracker during the high-luminosity phase of the LHC. The CBC2 is produced in a 130 nm CMOS technology and bump-bonded to the hybrid of the double layer silicon strip modules, the so-called 2S modules. It has 254 input channels and is designed to provide an on-board trigger with the capability of cluster-width discrimination and high-momentum track identification.

In November 2013 the first 2S module prototypes equipped with CBC2 were put under test at the DESY-II test beam facility. Data was collected exploiting a beam of positrons with an energy range of 2 to 4 GeV. The test setup, the event reconstruction, and the analysis results such as beam properties, alignment, clusters properties, and per-chip efficiency will be presented.
