Optical Link of the Atlas Pixel Detector
The on-detector optical link of the ATLAS pixel detector contains radiation-hard receiver chips to decode bi-phase marked signals received on PIN arrays and data transmitter chips to drive VCSEL arrays. The components are mounted on hybrid boards (optoboards). We present results from the irradiation studies with 24 GeV protons up to 32 Mrad (1.2 x 10 p/cm) and the experience from the production.
متن کاملThe ATLAS pixel detector
After a ten years planning and construction phase, the ATLAS pixel detector is nearing its completion and is scheduled to be integrated into the ATLAS detector to take data with the first LHC collisions in 2007. An overview of the construction is presented with particular emphasis on some of the major and most recent problems encountered and solved.
متن کاملA Novel Optical Package for ATLAS Pixel Detector
An optical package of novel design has been developed for the ATLAS pixel detector. The package contains two VCSELs and one PIN diode to transmit and receive optical signals. The design is based on a simple connector-type concept and is made of radiation-hard material. Several packages have been fabricated and show promising results.
متن کاملCommissioning of the ATLAS Pixel Detector
The ATLAS Pixel Detector is the innermost detector of the ATLAS experiment at LHC. Approximately 80 million silicon sensors allow to detect particle tracks and secondary vertices with very high precision. The ATLAS Pixel Detector is now in its final commissioning phase. A full characterization and qualification of the detector is currently performed: calibration procedures, special DAQ runs for...
متن کاملAn Optical Demo-Link for ATLAS Inner Detector Readout Upgrade
The GOL ASIC is a serializer chip developed by CERN based on a 0.25 μm CMOS technology [1]. The GOL operates with two data rates: 800 Mbps and 1.6 Gbps. This ASIC has been evaluated with radiation tolerance requirement for the ATLAS Inner Detector upgrade for the SLHC 1 . A demo-link has been designed and constructed to read out silicon detectors in the test staves through fiber optics. Through...
