Book excerpt: Experiments at Fermilab require an ongoing program of development for high speed, distributed data acquisition systems. The physics program at the lab has recently started the operation of a Fixed Target run in which experiments are running the DART[1] data acquisition system. The CDF and DØ experiments are preparing for the start of the next Collider run in mid 2000. Each will read out on the order of 1 million detector channels. In parallel, future experiments such as BTeV R & D and Minos have already started prototype and test beam work. BTeV in particular has challenging data acquisition system requirements with an input rate of 1500 Gbytes/sec into Level 1 buffers and a logging rate of 200 Mbytes/sec. This paper will present a general overview of these data acquisition systems on three fronts those currently in use, those to be deployed for the Collider Run in 2000, and those proposed for future experiments. It will primarily focus on the CDF and DØ architectures and tools.

Download or read book Networked Data Acquisition Systems Daq 96 Proceedings Of The Second International Data Acquisition Workshop written by Shuhei Ajimura and published by World Scientific. This book was released on 1997-07-15 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: This workshop followed the First International Conference, which was hosted by Fermilab, on 26-28 October, 1994. That conference discussed the switch type event builder. Much intensive R&D work ensued from it, showing the importance of (1) data flow control and (2) high speed memory access on network adapters/drivers. Those two themes are involved in many networked data acquisition systems. Therefore, “Networked Data Acquisition Systems” was selected as the theme of DAQ 96. It includes a wide variety of data acquisition system presentations from present and near-future experiments at high energy and nuclear physics laboratories.
Download or read book Run Control Techniques for the Fermilab DART Data Acquisition System written by and published by . This book was released on 1995 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: DART is the high speed, Unix based data acquisition system being developed by the Fermilab Computing Division in collaboration with eight High Energy Physics Experiments. This paper describes DART run-control which implements flexible, distributed, extensible and portable paradigms for the control and monitoring of data acquisition systems. We discuss the unique and interesting aspects of the run-control - why we chose the concepts we did, the benefits we have seen from the choices we made, as well as our experiences in deploying and supporting it for experiments during their commissioning and sub-system testing phases. We emphasize the software and techniques we believe are extensible to future use, and potential future modifications and extensions for those we feel are not.
Download or read book Data Acquisition with GPUs written by and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Graphical Processing Units (GPUs) have recently become a valuable computing tool for the acquisition of data at high rates and for a relatively low cost. The devices work by parallelizing the code into thousands of threads, each executing a simple process, such as identifying pulses from a waveform digitizer. The CUDA programming library can be used to effectively write code to parallelize such tasks on Nvidia GPUs, providing a significant upgrade in performance over CPU based acquisition systems. The muon $g$-$2$ experiment at Fermilab is heavily relying on GPUs to process its data. The data acquisition system for this experiment must have the ability to create deadtime-free records from 700 $\mu$s muon spills at a raw data rate 18 GB per second. Data will be collected using 1296 channels of $\mu$TCA-based 800 MSPS, 12 bit waveform digitizers and processed in a layered array of networked commodity processors with 24 GPUs working in parallel to perform a fast recording of the muon decays during the spill. The described data acquisition system is currently being constructed, and will be fully operational before the start of the experiment in 2017.

Available in PDF, EPUB and Kindle. Book excerpt: A new measurement of the anomalous magnetic moment of the muon, a? ≡ (g - 2)/2, will be performed at the Fermi National Accelerator Laboratory. The most recent measurement, performed at Brookhaven National Laboratory and completed in 2001, shows a 3.3-3.6 standard deviation discrepancy with the Standard Model predictions for a?. The new measurement will accumulate 21 times those statistics, measuring a? to 140 ppb and reducing the uncertainty by a factor of 4. The data acquisition system for this experiment must have the ability to record deadtime-free records from 700 ?s muon spills at a raw data rate of 18 GB per second. Data will be collected using 1296 channels of ?TCA-based 800 MSPS, 12 bit waveform digitizers and processed in a layered array of networked commodity processors with 24 GPUs working in parallel to perform a fast recording and processing of detector signals during the spill. The system will be controlled using the MIDAS data acquisition software package. Lastly, the described data acquisition system is currently being constructed, and will be fully operational before the start of the experiment in 2017.
Download or read book Integrating UNIX Workstation Into Existing Online Data Acquisition Systems for Fermilab Experiments written by and published by . This book was released on 1991 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the availability of cost effective computing prior from multiple vendors of UNIX workstations, experiments at Fermilab are adding such computers to their VMS based online data acquisition systems. In anticipation of this trend, we have extended the software products available in our widely used VAXONLINE and PANDA data acquisition software systems, to provide support for integrating these workstations into existing distributed online systems. The software packages we are providing pave the way for the smooth migration of applications from the current Data Acquisition Host and Monitoring computers running the VMS operating systems, to UNIX based computers of various flavors. We report on software for Online Event Distribution from VAXONLINE and PANDA, integration of Message Reporting Facilities, and a framework under UNIX for experiments to monitor and view the raw event data produced at any level in their DA system. We have developed software that allows host UNIX computers to communicate with intelligent front-end embedded read-out controllers and processor boards running the pSOS operating system. Both RS-232 and Ethernet control paths are supported. This enables calibration and hardware monitoring applications to be migrated to these platforms. 6 refs., 5 figs.

Download or read book Data Acquisition and Analysis for the Fermilab Collider RunII written by and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Operating and improving the understanding of the Fermilab Accelerator Complex for the colliding beam experiments requires advanced software methods and tools. The Shot Data Acquisition and Analysis (SDA) has been developed to fulfill this need. The SDA takes a standard set of critical data at relevant stages during the complex series of beam manipulations leading to (square root)(s) (almost equal to) 2 TeV collisions. Data is stored in a relational database, and is served to programs and users via Web based tools. Summary tables are systematically generated during and after a store. Written entirely in Java, SDA supports both interactive tools and application interfaces used for in-depth analysis. In this talk, we present the architecture and described some of our analysis tools. We also present some results on the recent Tevatron performance as illustrations of the capabilities of SDA.

The initial implementation of DART has concentrated on providing working data acquisition systems for the (now eight) collaborating experiments in the next Fixed Target Run. In this paper we discuss aspects of the architecture of DART and how these will allow it to be extended to meet the expected needs of future experiments at Fermilab. We also discuss some ongoing developments within the Fermilab Computing Division towards these new implementations.
Download or read book RF and Data Acquisition Systems for Fermilab s ILC SRF Cavity Vertical Test Stand written by and published by . This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Fermilab is developing a facility for vertical testing of SRF cavities as part of a program to improve cavity performance reproducibility for the ILC. The RF system for this facility, using the classic combination of oscillator, phase detector/mixer, and loop amplifier to detect the resonant cavity frequency and lock onto the cavity, is based on the proven production cavity test systems used at Jefferson Lab for CEBAF and SNS cavity testing. The design approach is modular in nature, using commercial-off-the-shelf (COTS) components. This yields a system that can be easily debugged and modified, and with ready availability of spares. Data acquisition and control is provided by a PXI-based hardware platform in conjunction with software developed in the LabView programming environment. This software provides for amplitude and phase adjustment of incident RF power, and measures all relevant cavity power levels, cavity thermal environment parameters, as well as field emission-produced radiation. It also calculates the various cavity performance parameters and their associated errors. Performance during system commissioning and initial cavity tests will be presented.
