The Reconfigurable Cluster Element (RCE) readout is a generic DAQ concept based on SoC building blocks with associated networking solution that was initially developed on an ATCA platform at SLAC in 2007. The combination of Gen-1 RCE on Virtex4/PowerPC and HSIO carried out the ATLAS pixel IBL stave QA/QC and installation commissioning in 2013. The RCE Gen-3 design migrated its base to the...
Many of the ATCA blades being proposed include some flavor of SoC on each blade. I will discuss where our SoC, a commercial Zynq 7000 series mezzanine board will fit in in our Apollo family of ATCA blades. The Apollo family of boards are made up of a services module, a command module, a SoC mezzanine, an Ethernet switch, and an IPMC. The services module is the primary board used for...
The Global Feature Extractor (gFEX) is a hardware jet trigger system that will be installed in the ATLAS experiment at CERN during Phase 1 upgrades. The gFEX will read out the entire calorimeter at the full LHC collision rate of 40 MHz and thus be able to calculate global quantities. This allows for the implementation of large-radius jet algorithms, potentially refined with jet subjet...
One of the ongoing technical challenges in experimental high energy physics is the real-time filtering (triggering) of data that may contain interesting interactions from a physics perspective. These challenges are especially pertinent on the hardware level for the general purpose LHC experiments since the first stage of triggering needs to simultaneously function on the order of tenths of...
From 2015 to 2018 the ATLAS Pixel detector has gradually been installing new readout drivers (RODs) that are used for data readout, configuration, monitoring, and calibration of the Pixel frontends. The RODs are 9U VME boards utilizing FPGA technology. The main FPGA is a Xilinx Virtex 5 Soc which contains a PPC440 processor. The processor is used to configure the frontend chips and to read...
In 2026, the LHC will be upgraded to the High Luminosity LHC (HL-LHC) allowing it to deliver up to 7 times the instantaneous design luminosity. The ATLAS Tile Calorimeter (TileCal) Phase-II Upgrade will accommodate the detector and data acquisition system to the HL-LHC requirements. The on- and off-detector readout electronics will be completely re-designed to cope with new data rates and...
During LS2, the legacy PreProcessor system of the ATLAS Level-1 Calorimeter Trigger (L1Calo) will be extended with new VME digital modules, called Tile Rear Extension (TREX). The main task of the TREX modules will be to extract copies of the Tile digitised results from the legacy trigger data path, and to transmit them to the new L1Calo Feature Extractor processors, via optical links running...
