The ATLAS level-1 calorimeter trigger hardware will be upgraded between the end of Run 2 and the start of Run 3. An overview of the hardware upgrades will be presented. Details of the algorithm design will be presented, along with the projected performance for electrons, jets and missing transverse momentum triggers.
The ATLAS experiment will undergo a series of upgrades during the 2019-2021 LHC shutdown to maintain physics performance in the increasingly harsh collision environment. The Front-End Link eXchange (FELIX) will be introduced into the readout system as part of this upgrade. FELIX will be the interface between the data acquisition; detector control and TTC (Timing, Trigger and Control) systems;...
This presentation will summarize the ECAL trigger performance achieved during LHC Run 2 (2015-2018). It will describe the methods that are used to provide frequent calibrations of the ECAL trigger primitives during LHC operation. These are needed to account for radiation-induced changes in crystal and photodetector response and to maintain stable trigger rates and efficiencies up to |eta|=3.0....
The new trigger system will be able to receive tracks reconstructed from silicon tracker hits by a level-1 track trigger and will evaluate algorithms that were previously reserved to the high-level trigger, such as vertex finding and particle flow. The final element in the level-1 trigger, the Global Trigger, will receive a large number of physics object collections reconstructed with...
A highly granular silicon-tungsten electromagnetic calorimeter (SiW-ECAL) is the reference design of the ECAL for International Large Detector (ILD) concept, one of the two detector concepts for the detector(s) at the future International Linear Collider. Prototypes for this type of detector are developed within the CALICE Collaboration. Since 2019 a highly compact digital read out card,...
The current Vertex Locator (VELO) detector will be replaced from strips to pixels in the LHCb upgrade in 2020. This work focuses on the architecture of the readout chain and the challenges of the high speed data transmission and processing. The readout is divided in 3 parts: frontend VeloPix ASIC, the control and timing interface ASIC (GBTx), and the the FPGA backend board. The VeloPix is a...
During LS3, the CMS Detector will undergo a major upgrade for the Phase-2 of the LHC physics program, starting around 2027. The upgraded CMS detector will be read out at a data rate of up to 50 Tb/s with an event rate of 750 kHz, selected by the level-1 hardware trigger, and an average event size of 8 MB. We present the baseline design of the DAQ.
A DAQ and Timing Hub (DTH) board acts as an...
Serenity is a data-processing platform designed for use in the HL-LHC upgrades of the CMS tracker, endcap calorimeter and level-1 trigger, whose electronics systems will consist of several hundred cutting-edge boards connected by tens of thousands of high-speed optical links. The Serenity ATCA blade provides common services, including up to 11.6Tb/s of optical I/O and an on-board CPU. The...
The Jiangmen Underground Neutrino Observatory (JUNO) is the second phase of the reactor neutrino experiment upgrade from the Daya Bay Reactor Neutrino Experiment. The detector of the experiment was designed as 20k ton LS with an inner diameter of 34.5 meters casting material acrylic ball shape. Due to the gigantic shape of the detector there are approximate 400k channels of monitoring points...
The DUNE detector is a long baseline neutrino experiment due to take data in 2025. The data acquisition system of the DUNE experiment will consist of a complex and distributed architecture designed to handle O(5) TB/s of incoming data from the readout system at a rate of 2 MHz.
One of the physics goals of the DUNE experiment is to detect neutrino signals from Supernova Burst events. These...
Commissioning of readout electronics for the Belle II K-Long and Muon (KLM) detector is discussed. Belle II is located at the interaction point of the SuperKEKB particle collider in Tsukuba, Japan. The KLM subdetector, formerly made solely from resistive-plate counters, has been partially upgraded with polyvinyltoluene scintillating bars, each covered in a TiO$_2$ reflective coating, embedded...
Belle ll experiment at SuperKEKB, high luminosity electron-positron collider, searches for new physics by consucting a detailed measurements of B meson and tau particles. In order to trigger physics events with high efficiency under high background environment, we developed level-1 trigger system based on central drift camber and electromagnetic calorimeter. We describe an overview of our...
The ATLAS collaboration at LHC has chosen resistive Micromegas technology and small-strip Thin Gap Chambers (sTGC) for the high luminosity upgrade of the first muon station, New Small Wheel (NSW), in the high-rapidity region. Both technologies provide trigger and precision tracking. A total number of 768 pad Front-end Boards (pFEB), 768 strip Front-end Boards (sFEB) and 512 Level-1 Data Driver...
The Jiangmen Underground Neutrino Observatory (JUNO) is a multi-purpose underground neutrino experiment. About 18000 20-inch photomultipliers (PMTs) are instrumented in the Central Detector to detect the photons, and the signals will be captured by high-speed high-resolution waveform full sampling technique. This work builds a prototype DAQ system for JUNO, which can be used to test the full...
