164. FELIX: the new detector readout system for the ATLAS experiment

Julia Narevicius (Weizmann Institute of Science (IL))

Upgrades

Oral presentation

From the ATLAS Phase-I upgrade and onward, new or upgraded detectors and trigger systems will be interfaced to the data acquisition, detector control and timing (TTC) systems by the Front-End Link eXchange (FELIX). FELIX is the core of the new ATLAS Trigger/DAQ architecture. Functioning as a router between custom serial links and a commodity network, FELIX is implemented by server PCs with...

136. Upgrade of the TOTEM data acqusition system for the LHC's Run Two

Upgrades

Oral presentation

The TOTEM (TOTal cross section, Elastic scattering and diffraction dissociation Measurement at the LHC) experiment at LHC, has been designed to measure the total proton-proton cross-section with a luminosity independent method, based on the optical theorem, and to study the elastic and diffractive scattering at the LHC energy. To cope with the increased intensity of the LHC run 2 phase, and...

146. Phase-I Trigger Readout Electronics Upgrade for the ATLAS Liquid-Argon Calorimeters

Nicolas Chevillot (Centre National de la Recherche Scientifique (FR))

Upgrades

Oral presentation

For the Phase-I luminosity upgrade of the LHC, a higher granularity trigger readout of the ATLAS LAr Calorimeters is foreseen in order to enhance the trigger feature extraction and background rejection. The new readout system digitizes the detector signals, which are grouped into 34000 so-called Super Cells, with 12-bit precision at 40 MHz. The data is transferred via optical links to a...

205. Large-scale DAQ tests for the LHCb upgrade

Antonio Falabella (Universita e INFN, Bologna (IT))

Upgrades

Oral presentation

The Data Acquisition (DAQ) of the LHCb experiment will be upgraded in 2020 to a high-bandwidth triggerless readout system. In the new DAQ event fragments will be forwarded to the to the Event Builder (EB) computing farm at 40 MHz. Therefore the front-end boards will be connected directly to the EB farm through optical links and PCI Express based interface cards. The EB is requested to provide...
