CBC2 Test Beam Analysis
The CMS Binary Chip 2 (CBC2) is a prototype version of the front-end readout ASIC to be used in the silicon strip modules of the CMS outer tracker during the high-luminosity phase of the LHC. The CBC is produced in a 130nm CMOS technology and bump-bonded to the hybrid of the double layer silicon strip modules, the so-called 2S modules. It has 245 input channels and is designed to provide on-board trigger with the capability of cluster width discrimination and high-Pt track identification. In November 2013 two 2S module prototypes equipped with CBC2 were tested at the DESY-II test beam facility. Data was collected exploiting a beam of positrons with an energy range from 2 to 4 GeV. Angular and threshold scans were carried out, and more than 500 runs were recorded
The aim of the hands-on exercise is to analyze the test beam data using a set of angular scan runs in order to compare the stubs behavior at different angles.
Detailed descriptions on the exercise can be found in
