Operational experience with the ALICE Pixel Detector
The ALICE Silicon Pixel Detector (SPD) constitutes the innermost detector of the ALICE experiment, which is the LHC experiment dedicated to the investigation of strongly interacting matter in heavy-ion collisions. The SPD consists of ∼10 million pixels organized in two layers at radii of 39 mm and 76 mm that cover a pseudorapidity range of |η |< 2 and |η |< 1.4, respectively. It provides the po...
متن کاملCalibration of the Prompt L0 Trigger of the Silicon Pixel Detector for the ALICE Experiment
The ALICE Silicon Pixel Detector (SPD) is the innermost detector of the ALICE experiment at LHC. It includes 1200 front-end chips, with a total of ~10 pixel channels. The pixel size is 50 x 425 μm. Each front-end chip transmits a Fast-OR signal upon registration of at least one hit in its pixel matrix. The signals are extracted every 100 ns and processed by the Pixel Trigger (PIT) system, to ge...
متن کاملBeam Test Performance and Simulation of Prototypes for the ALICE Silicon Pixel Detector
The silicon pixel detector (SPD) of the ALICE experiment in preparation at the Large Hadron Collider (LHC) at CERN is designed to provide the precise vertex reconstruction needed for measuring heavy flavor production in heavy ion collisions at very high energies and high multiplicity. The SPD forms the innermost part of the Inner Tracking System (ITS) which also includes silicon drift and silic...
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 کاملThe ALICE Pixel Detector Readout Chip Test System
The ALICE experiment will require some 1200 Readout Chips for the construction of the Silicon Pixel Detector [1] and it has been estimated that approximately 3000 units will require testing. This paper describes the system that was developed for this task.
