A new Silicon Tracker will be built for the Phase 2 Upgrade of the CMS experiment. The innermost part, called the Inner Tracker, will be featuring high-granularity pixelated silicon sensors and will need to cope with extreme radiation levels and hit rates. The pixel electronics system is based on innovative solutions such as a new pixel ASIC developed by the RD53 collaboration, the novel...
To meet new TDAQ buffering requirements and withstand the high expected radiation doses at the high-luminosity LHC, the ATLAS Liquid Argon Calorimeter readout electronics will be upgraded. Developments of low-power preamplifiers and shapers and of a low-power 40 MHz 14-bit ADCs are ongoing. The signals will be sent at 40 MHz to the off-detector electronics, where FPGAs connected through...
The Mu3e experiment searches for the lepton flavour violating decay µ→ eee with an ultimate aimed sensitivity of 1 event in 10^16 decays. This goal can only be achieved by reducing the material budget per tracking layer to X/X0 ≈ 0.1%. For this purpose, the vertex detector is based on HV-MAPS thinned to 50 µm. Also, the powering and data transmission is performed by means of kapton-aluminum...
The challenging conditions of High-Luminosity LHC (HL-LHC) require tailored hardware designs for the trigger and data acquisition systems. The Apollo platform features a "Service Module" (SM) with a powerful system-on-module (SoM) computer that provides standard ATCA communications and application-specific "Command Module"s (CM) with large FPGAs and high speed optical fiber links. The CMS...
The building blocks of the upgraded ATLAS Strip Tracker for HL-LHC are modules that host silicon sensors and front-end ASICs. The modules are mounted on carbon-fibre substructures hosting up to 14 modules per side. An End-of-Substructure (EoS) card on each substructure connects up to 28 differential data lines at 640 Mbit/s to lpGBT and VL+ ASICs that provide data serialisation and 10 GBit/s...
The frontend readout system for the silicon section of the CMS Phase II Endcap Calorimeter faces unique challenges due to the high channel count and associated bandwidth, limited physical space, as well as radiation tolerance requirements. This presentation will give an overview of the frontend electronics design and will discuss the recent experience obtained from the first test system that...
RPC detectors are used to trigger muons in the ATLAS Muon Spectrometer barrel region. The foreseen HL-LHC operation imposes replacing their trigger and readout electronics with a data collector and transmitter (DCT) system, which implements the LPGBT optical link to handle data bandwidth up to 10.24Gb/s. A testing system will be implemented to assess all DCT prototypes and mass production....
An overview of the electronics readout/trigger architecture for the CMS HGCAL will be given. To respond to physics performance requirements, data rates, trigger-primitive generation and radiation tolerance has been extremely challenging. Each HGCAL endcap includes ∼300m² of active silicon in 50 layers, with a largely inhomogenous layout with limited commonality between layers. An agile,...
The main goal of the Jiangmen Underground Neutrino Observatory (JUNO) under construction in China is to determine the neutrino mass hierarchy. The detector consists of 20 ktons of liquid scintillator instrumented by 17612 20-inch photomultiplier tubes, and 25600 3-inch small PMTs, with photocathode coverage of 77%. The electronics system is separated into two main parts. The front-end system,...
For the Phase 2 of the LHC, the central electromagnetic (EB) and hadronic (HCAL) calorimeters of the CMS experiment require a new back-end electronics for its readout. The first version of the ATCA-based blade, the Barrel calorimeter processor (BCPv1), has been developed with a large flexibility to allow evaluation of the different strategies. The performance of the optical links as well as...
Future particle trackers will have to measure concurrently position and time with unprecedented resolutions, approximately 5 microns and 10 ps respectively. A promising good candidate are the AC-LGADs, silicon sensors of novel design, with internal gain and an AC-coupled resistive read-out to achieve signal sharing among pads. This design leads to a drastic reduction of read-out channels, has...
Sixteen thousand 2S front-end hybrids and twelve thousand PS front-end hybrids will be produced for the CMS Tracker Phase-2 Upgrade. The hybrids consist of flip-chips, passives and mechanical components mounted on a flexible substrate, laminated onto carbon-fibre stiffeners with thermal expansion compensators. In the prototyping phase, several critical issues have been solved to manufacture...
The CMS Tracker Phase 2 Upgrade modules integrate DCDC powering stages and an optical transceiver to power and control the front-end hybrids. The strip-strip (2S) module contains a Service Hybrid (2S-SEH) with two stage DC-DC power conversion, an lpGBT with optical interface (VTRx+), high voltage biasing and temperature sensor ports. The pixel-strip (PS) module utilizes a separate two stage...
The Compressed Baryonic Matter (CBM) experiment is designed to handle interaction rates of up to 10 MHz and up to 1 TB/s of raw data generated. With free-streaming data acquisition in the experiment and beam intensity fluctuations, it is expected that occasional data bursts will surpass bandwidth capabilities of the Data Acquisition System (DAQ) system. In order to preserve event data, the...
The CMS detector will undergo a major upgrade for Phase-2 of the LHC program: the HiLumi LHC. The Phase-2 CMS back-end electronics will be based on the ATCA standard, with node boards receiving the detector data from the front-ends via custom,
radiation-tolerant, optical links. An ATCA hub board, the DAQ and Timing Hub, will provide the interface between the back-end nodes and the central...
When the RD51 collaboration formed in 2008, the community initiated efforts for a standardised common readout system, the Scalable Readout System (SRS). The APV25 chip, originally designed for the CMS silicon strip detector, was the working horse within the first decade reading out gaseous detectors. Meanwhile, the VMM chip has taken over and further ASICs were (Timepix, SiPMs) or are...
The Front-End Link eXchange (FELIX) system is a new ATLAS DAQ component designed
to for detector readout in the High-Luminosity LHC era. FELIX acts as the interface
between the data acquisition, detector and trigger timing systems. FELIX routes data between
custom serial links from front-end electronics to data collection and processing components
via a commodity switched network. This...
The ALICE Inner Tracking System has gone through a significant upgrade for the upcoming third running period of the CERN LHC. The new detector consists of seven layers of high-granularity pixel sensors, while 192 custom FPGA-based readout units control the sensors and transmit the data upstream for analysis. This contribution describes the current system status and the expertise gained by...
