DAQFEET-2021

8 Feb 2021, 09:30 → 10 Feb 2021, 17:00 Europe/Prague

ZOOM

Current DAQ systems contain many complex parts and subsystems that have to provide the best possible performance. Therefore, these modules undergo intensive developments and innovations in order to keep up with the latest requirements of HEP experiments. The future of acquisition systems relies on advanced technologies, state-of-the-art hardware, and software solutions. Moreover, these modern DAQ systems usually include streaming data formats and triggerless techniques, which will be discussed in this workshop.

This workshop is focused on the development of modern data taking for experiments beyond 2020. It will be hosted online on February 8-10, 2021. We will discuss the required performance and architecture of FEE and DAQ components, unify serial interfaces and protocols, discuss trigger processor hardware, and distribution of workload. This time we aim to have presentations from a broader range of experiments to share experiences and discuss the future. Workshop will take place at zoom.

This presentation will outline the latest developments and findings with VMM3a. It reports on several activities carried out within the RD51 collaboration using the general Scalable Readout System. After the ASIC has been integrated within the last years, the first commercial production of joint orders by many teams was just completed. In several projects, the system was improved, a QA system was developed and properties of the chip like noise, time and energy resolution were studied.

12:00 ARCADIA: Fully Depleted CMOS MAPS technology

ARCADIA is an INFN R&D Platform for the design, fabrication and system integration of fully-depleted CMOS monolithic sensors and associated electronics, firmware and software.
The Collaboration developed a novel sensor technology allowing for:
- Active sensor thickness in the range 50 μm to 500 μm or more;
- Operation in full depletion with fast charge collection only by drift;
- Small charge collecting electrode for optimal signal-to-noise ratio;
- Scalable readout architecture with ultra-low power capability;
- Compatibility with standard CMOS fabrication processes.
We will present the ongoing activities and future perspectives towards the use of the ARCADIA CMOS DMAPS technology on future HEP infrastructures.

09:00 Modern trends in programming for GPUs

We will present modern GPU architectures and their advantages compared to CPUs. We will also discuss modern trends in GPU programming which should make this very powerful architecture easily available even to scientists who do not have deep knowledge about the design of GPUs.

09:30 Use of the GPUs in radio astronomy

Abstract: GPUs are widely used in many areas of science, scientific computing and real-time data processing. In this talk, I will briefly introduce some of GPUs' uses in the (near) real-time data processing in radio astronomy for the Square Kilometre Array (SKA) radio telescope. The Square Kilometre Array (SKA) is an international initiative for developing the world's largest radio telescope with a total collecting area of over a million square meters. The data processing in radio astronomy is for the most part low in arithmetical intensity which necessitated good data reuse in the GPU implementations, and it has to deal with an unknown of inputs or number of samples on vastly different scales. A particular example of this is when an image is reconstructed from frequency-domain data (gridding) and when an image is transformed back to frequency domain (de-gridding) in the iterative image cleaning process.

10:10 32 Tb/s DAQ for the LHCb experiment at CERN

The currently-commissioned LHCb data acquisition system for Run3 will collect data in runtime at 32 Tbit/s. The new version of the customized cluster will implement a fully software-defined selection of uncompressed FPGA streams. The principle of LHCb's operation enforces all-to-all lossless communication to assemble scattered data for further real-time selection. The cost-optimized architecture consists of the network and the servers that operate at close-to-the-link and close-to-the-memory-throughput capacity. The aim is to ultimately output into storage heavily compressed events at a much-reduced throughput of 1 Gigabit per second. This talk presents the most important development and commissioning decisions and lessons learned along the road. Topics of front-end FPGAs, tested networks, evaluation-based choice of hardware, and commissioning are covered.

11:10 Electronics for GEM Detectors - Recent Developments

Multi-GEM detectors are widely used for the tracking of charged particles with good spatial resolution at high luminosity, while using only a very low material budget. For the COMPASS experiment at CERN, the third generation of these detectors is currently being constructed, while and the fourth generation is under development.

This talk presents the most recent improvements on the readout and auxiliary electronics for these detectors. A new stabilized high-voltage divider offers both a more stable operation under varying detector currents and an improved protection in case of short circuits in GEM foils. A new revision of APV frontend cards is currently being produced. The new revision includes specialized ESD protection diodes which have a lower parasitic capacitance while offering a better protection against discharges.
The protection circuit was tested with a custom-built discharge simulator which is able to deliver surges with well reproducible characteristics.

16:30 Monitoring tools for future

The planned transition to the new FriDAQ data format requires significant modifications of the current DAQ software. Highly affected parts include monitoring tools COOOL and MurphyTV, and related DaqDataDecoding library. In the presentation, a student project aiming to facilitate the adjustment of the mentioned programs is introduced. The talk contains a summary of the initial state, a discussion of the scale of necessary changes, and an outline of further work
