Sensor simulation and position calibration for the CMS pixel detector
In this paper a detailed simulation of irradiated pixel sensors was used to investigate the effects of radiation damage on charge sharing and position determination. The simulation implements a model of radiation damage by including two defect levels with opposite charge states and trapping of charge carriers. We show that charge sharing functions extracted from the simulation can be parameteri...
متن کاملCMS Silicon Pixel Detector Calibration
The Compact Muon Solenoid (CMS) pixel group at Cornell University is building a silicon pixel detector test station that will model the detection and data acquisition system designed for the CMS experiment at the Large Hardron Collider (LHC) at CERN. With parts of the apparatus already functional, we have begun to understand and optimize the detector’s programmable settings, called DACs, that t...
متن کاملCMS pixel detector — overview
Pixel detectors are being built for use at the Large Hadron Collider beginning in the year 2007. We present an overview of the Compact Muon Solenoid Pixel Detector effort. r 2003 Elsevier B.V. All rights reserved. PACS: 13.20.Fc; 13.30.Ce; 14.40.Lb
متن کاملRadiation experience with the CMS pixel detector
The CMS pixel detector is the innermost component of the CMS tracker occupying the region around the centre of CMS, where the LHC beams are crossed, between 4.3 cm and 30 cm in radius and 46.5 cm along the beam axis. It operates in a high-occupancy and high-radiation environment created by particle collisions. Studies of radiation damage effects to the sensors were performed throughout the firs...
متن کاملTests of silicon sensors for the CMS pixel detector
The tracking system of the CMS experiment, currently under construction at the Large Hadron Collider (LHC) at CERN (Geneva, Switzerland), will include a silicon pixel detector providing three spacial measurements in its final configuration for tracks produced in high energy pp collisions. In this paper we present the results of test beam measurements performed at CERN on irradiated silicon pixe...
