Readout and Trigger for the AFP Detector at ATLAS Experiment
نویسنده
چکیده
AFP, the ATLAS Forward Proton consists of silicon detectors at 205 m and 217 m on each side of ATLAS. In 2016 two detectors in one side were installed. The FEI4 chips are read at 160 Mbps over the optical fibers. The DAQ system uses a FPGA board with Artix chip and a mezzanine card with RCE data processing module based on a Zynq chip with ARM processor running ArchLinux. In this contribution we give an overview of the AFP detector with the commissioning steps taken to integrate with the ATLAS TDAQ. Furthermore first performance results are presented.

Trigger-less readout architecture for the upgrade of the LHCb experiment at CERN F Alessio Development of a Standardised Readout System for Active Pixel Sensors in HV/HR-CMOS Technologies for ATLAS Inner Detector Upgrades
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 کاملEvaluation of an FPGA and PCI bus based readout buffer for the Atlas experiment
This dissertation evaluates a readout buffer system for the ATLAS detector trigger and data acquisition system. ATLAS is a high energy physics experiment at the large hadron collider (LHC) with the aim to reach new frontiers in the investigation of the structure of matter. The high precision ATLAS detector produces a huge amount of data, 40 TByte/s, which is reduced by a three-level trigger sys...
متن کاملElectronics Design and System Integration of the ATLAS New Small Wheels
The upgrades of the Large Hadron Collider (LHC) at CERN and the experiments in 2019/20 and 2024/26 will allow to increase the instantaneous luminosity to L = 2 × 1034 cm−2s−1 and L = 5 − 7 × 1034 cm−2s−1, respectively. For the High Luminosity (HL) HL-LHC phase, the expected mean number of interactions per bunch crossing will be 55 at L = 2 × 1034 cm−2s−1 and 140 at L = 5 × 1034 cm−2s−1. This in...
