The present small wheel muon detector at ATLAS will be replaced with a New Small Wheel (NSW) detector to handle the expected rate at the increase in data rates and harsh radiation environment expected at the LHC. Resistive Micromegas and small-strip Think Gap Chambers will be used to provide both trigger and tracking primitives. A new trigger and readout system is developed for the NSW...
NEBuLA is a large band autonomous digitiser under development, with use cases in radio astronomy.
We present the scientific rationale and the specifications of the project, We describe the board overall architecture,
the implementation of the different links: synchronisation, command, control and data transfer. We present
the solution adopted to fulfil the main requirement of the project...
The DAQ of the CLICpix2 readout chip is based on the Control And Readout Inner tracking BOard (CaRIBOu). CaRIBOu is a versatile readout system targeting a multitude of detector prototypes. It profits from the heterogeneous platform of the Zynq System-on-Chip and integrates in a monolithic device front-end FPGA resources with a back-end software running on a hard-core ARM-based processor. The...
The design and implementation of demonstrator front-end electronics for Micromegas detectors to be employed in the New Small Wheel, an ATLAS muon spectrometer upgrade, are presented. The demonstrator has 512 Micromegas detector channels as input. Signal processing and digitization utilize a custom ASIC developed by Brookhaven National Lab. Configuration, control and Ethernet readout...
The Time of Propagation (TOP) detector is a novel Cherenkov barrel particle identification system built for the Belle II detector upgrade based on quartz radiator bars read out by Micro-Channel Plate PMTs. The readout electronics of the TOP system are built around a switched capacitor array waveform sampling ASIC operating at 2.7GSa/s. Acquired waveforms are processed in real time in...
The LHCb Experiment will be upgraded to a trigger-less system reading out the full detector at 40
MHz event rate with all selection algorithms executed in a CPU farm. The upgraded Vertex Locator
(VELO) will be a hybrid pixel detector read out by the "VeloPix" ASIC with on-chip zero-suppression.
This talk will present the systems overview and design of the VELO on-detector electronics...
The High-Luminosity LHC (HL-LHC) is planned to start the operation in 2026 with an instantaneous luminosity of 7.5 x 1034 cm-2s-1. To cope with the event rate higher than that of LHC, the trigger and readout electronics of ATLAS Thin Gap Chamber will be replaced and an advanced muon trigger with fast tracking will be implemented. A frontend board prototype was developed and the functions for...
Following the first LHC collisions seen and recorded by CMS in 2009, the DAQ hardware went through a major upgrade during LS1 (2013-2014) and new detectors have been connected during the 2016-2017 winter shutdown. Now, LS2 (2019-2020) and LS3 (2024-mid 2026) are actively prepared. This paper shows how CMS DAQ hardware has evolved from the beginning and will continue to evolve in order to meet...
In 2016, a TTC-PON (Timing, Trigger and Control system based on Passive Optical Networks) demonstrator was presented at TWEPP as an alternative to replace the TTC system, currently responsible for delivering timing, trigger and control commands in the LHC experiments. Towards a deployment foreseen for ALICE phase-1 upgrade, the system has been consolidated through flexible software...
We present the readout system being designed for triple-GEM detectors to be installed in 2019-2020 in the CMS muon endcap for HL-LHC. Beginning of 2017, 10 triple-GEMs have been installed in CMS. These detectors are read-out with the VFAT2 chip while its next version, the VFAT3, is under characterization. The rest of the readout system is very similar between the 2017 and the final version:...
During the extended year-end technical stop 2016/17 the CMS Pixel Detector has been replaced. The new Phase 1 Pixel Detector is designed for a luminosity that could exceed L = 2x10^34 cm^-2 s^-1. With one additional layer in the barrel and the forward region of the new detector, combined with the higher hit rates as the LHC luminosity increases, these conditions called for an upgrade of the...
Using FPGA technology for event building tasks in high-energy physics experiments reduces costs and increases reliability of DAQ systems. In 2014, the COMPASS experiment at CERN’s SPS commissioned a novel, intelligent, FPGA-based DAQ (iFDAQ) in which event building is entirely performed by FPGA cards. The highly scalable system is designed to cope with an on-spill data rate of 1.5 GB/s and a...
Metallic magnetic calorimeters (MMC) are new cryogenic detectors that offer a high resolution of single eV, a signal rise time of below 100 ns, a dynamic spectrum of several 10 keV and an almost optimal linearity. MMCs are of high interest for many experiments, such as dark matter detection or neutrino mass specification. Since pixel arrays of the sensor are read out at GHz-Frequency and each...
The upgrade of the Compact Muon Solenoid (CMS) crystal electromagnetic calorimeter (ECAL), which will operate at the High Luminosity Large Hadron Collider (HL-LHC), will achieve a timing resolution of around 30 ps for high energy photons and electrons. We will discuss the benefits of precision timing for the ECAL event reconstruction at HL-LHC. Simulation studies on the timing properties of...
Electronics developments are pursued for the trigger readout of the ATLAS Liquid-Argon Calorimeter towards the Phase-I upgrade scheduled in the LHC shut-down period of 2019-2020. The LAr Trigger Digitizer system will digitize 34000 channels at a 40 MHz sampling with 12 bit precision after the bipolar shaper at the front-end system, and transmit to the LAr Digital Processing system in the...
