An Optical Demo-Link for ATLAS Inner Detector Readout Upgrade
نویسندگان
چکیده
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 this demo-link we plan to study system issues in a giga-bit optical link. This concept will be extended to future serializer ASICs like the GBTx and the LOC when they become available. Experience gained from these demolinks will help us design and build a reliable optical readout system for new ATLAS Inner Detector readout.

The LHCb experiment is upgrading part of its detector and the entire readout system towards a full 40 MHz readout system in order to run between five and ten times its initial design luminosity and increase its trigger efficiency. In this paper, the new timing , trigger and control distribution system for such an upgrade is reviewed with particular attention given to the distribution of the clo...
متن کاملA Serializer ASIC at 5 Gbps for Detector Front-end Electronics Readout
Optical data links are used in detector front-end electronics readout systems of experiments in the Tevatron and the LHC. Optical links in high energy particle physics experiments usually have special requirements such as radiation tolerance, ultra high reliability and low power dissipation. These requirements are often not met by commercial components which are designed for applications in non...
متن کاملThe Phase II ATLAS Pixel Upgrade: The Inner Tracker (ITk)
The entire tracking system of the ATLAS experiment will be replaced during the LHC Phase II shutdown (foreseen to take place around 2025) by an all-silicon detector called the ITk (Inner Tracker). The pixel detector will comprise the five innermost layers, and will be instrumented with new sensor and readout electronics technologies to improve the tracking performance and cope with the HL-LHC e...

I n 2013 during a 20 month long shutdown of the LHC the Pixel Detector of the ATLAS Experiment at CERN will be upgraded by inserting a fourth innermost layer between the beam pipe and the current detector. This so called Insertable B-Layer (IBL) will be constructed with 448 of the new FE-I4 chips to handle the readout of the about 12 million pixels provided by the sensors of this layer. The imp...
متن کاملTracking detectors for the LHC upgrade
The plans for an upgrade of the Large Hadron Collider LHC to the Super-LHC (sLHC) are reviewed with special consideration of the environment for the inner tracking system. A straw-man detector upgrade for ATLAS is presented, which is motivated by the varying radiation levels as a function of radius, and choices for detector geometries and technologies are discussed in the context of required si...
