The first prototypes of the HL-LHC electronics for the CMS On detector Board for the Drift Tube chambers (OBDT) have been installed attached to the DT chambers of the CMS detector and integrated in the central data acquisition and trigger system. They have operated together with the first backend prototypes for trigger generation and slow control. Months long data taking campaign of cosmic...
The ATLAS level-1 calorimeter trigger (L1Calo) is a hardware system that identifies events containing calorimeter-based physics objects. In preparation for Run 3 with increased pileup (mu~65), L1Calo is currently implementing a significant programme of planned upgrades. The existing hardware will be replaced by a new system of feature extractor (FEX) modules with improved input granularity...
The Phase-II upgrade of the ATLAS experiment requires a redesign of the DAQ system, which will need to sustain 5.2 TB/s of input data for a rate of 1 MHz and provide access to 3 TB/s of these data to an event filtering farm. A possible implementation of the storage system consists of having a large storage buffer capable of decoupling the data readout from the data selection subsystem. DAQDB...
We present the development of a simulation tool for the synthesis and simulation of Continuous-Time (CT) Delta Sigma (โโ) ADC. For this, we decided to use a Model-based design approach which it is adopted to design such complex system. Our goal is the design of a 10 bit ENOB ADC for energy measurement systems used in particle identification through a new generation of detectors based on CVD...
The CBM heavy ion experiment at the GSI/FAIR facility will employ GBTX and VersatileLink devices in five subdetectors in a free streaming readout system at interaction rates up to 10^7/s starting from 2025.
Currently prototype and medium scale preseries readout systems are used for precursor experiments in the FAIR-Phase-0 program both at GSI (mCBM) and at BNL (eTOF@STAR).
We present the...
We present a free and open source firmware designed to operate as an Intelligent Platform Management Controller (IPMC). OpenIPMC is based on the FreeRTOS real-time operating system and is designed to be architecture-independent, allowing it to be run on a variety of different architectures. It has been tested successfully on Zynq Ultrascale+ (ARMv7-R) and ESP32 (Tensilica Xtensa LX6) devices....
The Bern cyclotron is an 18 MeV proton accelerator that is used to irradiate samples with a total ionising dose-rate ranging from 10 to 20^3 rad/s (10^8 to 10^11 1MeV n_{eq}/(cm^2 s)). Using a setup including beam monitoring, current measurements and a flexible infrastructure to mount samples, the setup allows testing for radiation hardness of samples (electronics, silicon sensors, cables)...
The upgrade of the ATLAS TileCal LVPS falls under the HL-LHC upgrade. This upgrade is composed of multiple projects that when combined will form the latest iteration of the LVPS. One such project is focused on an LVPS component known as a brick. These bricks function to step-down bulk 200V DC current to the 10V DC current required by the front-end electronics of a TileCal module and are...
The ALDOv2 ASIC is a multi-purpose adjustable low dropout linear regulator designed in I3T80 $\mathrm{0.35\ \mu m}$ HV CMOS technology. It is specifically designed for the CMS Barrel Timing Layer (BTL) detector and its purpose is twofold: to provide the final voltage regulation for the BTL front-end chip (TOFHIR) and slow control chip (GBT-SCA), cascaded to a DCDC converter; to provide the...
The TileCoM mezzanine board is one of the auxiliary boards of the TilePreProcessor (TilePPr) for Phase-2 Upgrade of the readout electronics of ATLAS TileCal. The TileCoM si responsible for remotely configuring the on-detector electronics and TilePPr-FPGAs and to interface ATLAS DCS-data to TilePPr. The TilePPr is composed of several FPGA-based boards to operate and read-out the on-detector...
KARATE (KArlsruher high RAte TEst) is a new test system to stress the readout chain of 2S modules for the future CMS Outer Tracker. Standard test systems such as test beams or radioactive source measurements do not reach the occupancy and trigger rates expected on 2S modules. KARATE uses a combination of LEDs and photodiodes to inject variable hit patterns into the front-end of a CMS Binary...
The all-silicon inner tracker (ITk) envisioned for ATLAS HL-LHC upgrade features a high-speed, radiation-hard data transmission system for the Pixel Detector, of which a key stage is the electrical-to-optical conversion, which combines multiple electrical signals into an optical signal. This includes dedicated application specific integrated circuits to restore attenuated signals from the...
The endcap region of HCAL detector (HE) and Barrel HCAL Detector (HB) is now readout by Silicon Photomultiplier (SiPM) which are immune to the magnetic field.The SiPM Control Board, which is installed in the SiPM Readout Module (RM), provides the SiPMs with programmable individual bias voltage,measures SiPM Bias Voltage currents,drives Peltier element for SiPM cooling,measures the temperature...
We present two test-station designs for testing the latest version of a switch-mode power supply for the front-end electronics of the ATLAS TileCal. The new test-station significantly improves fault detection and reliability. We further discuss the steps taken to test the new Tile-LVPS, using a custom-based software to perform tests and graphically display and record all performance metrics....
The RCE (Reconfigurable Cluster Element) platform is a general-purpose system-on-chip design data acquisition system, deployed by many experiments like ATLAS, LCLS, LSST, HPS, and ProtoDUNE. We present a new generation bench-top RCE system, including a Xilinx UltraScale+ MPSoC board and a custom FMC adaptor card, which is a prototype pixel readout chips for the Phase II upgrade of ATLAS and...
The Embedded Local Monitor Board version 2 (ELMB2) is a fully backward compatible upgraded version of the ELMB, widely used in LHC systems and experiments for slow-control and monitoring purposes. The substitution of the most vulnerable components led to an improved performance and a higher radiation tolerance compared to its predecessor. The SEE rates, TID and NIEL effects were evaluated at 3...
The poster shows the work done in the last years to improve the maintainability of the turbine crates for LHC racks. With this new design, the motor-ventilator units can be extracted and exchanged inside the crate without having to remove it from the rack. This is of particular importance for those units located close to detector magnets (heavily shielded).
