  1. “DAQ” at the El. Pool • Aim and preconditions • Hardware • Operating system support • Low level software • Middle level software • High level software • Other services • Possibilities

  2. Aim and preconditions • Background • Staff of EP-ESS group has always contributed at different levels to the DAQ systems of the many small experiments in the past and the to the development of the LHC experiments • In recent years we have focused more on specific contributions rather than the provision of complete systems • Aim • With your help we would like to assess the possibility of offering a more comprehensive service for “small” DAQ applications as one finds them in small experiments and test-beams. • Resources • EP-ESS is able to contribute one FTE engineer (2 or 3 physical persons) and one fellow (full time) • A successful extrapolation o the services provided by EP-ESS so far depends crucially on the collaboration with other experimental and service groups

  3. Hardware - VME64x crates • Mechanics: IEEE1101.1, .10, .11 • Backplanes: VME64x (with P0) or custom • Power supplies: Remote & local, air and water cooled or custom • Remote control & monitoring: CAN, Ethernet, OPC server • Procurement: Frame contract with W-Ie-Ne-R Plein & Baus (after Invitation to Tender) • Price examples: • 6U VME64x complete with local air-cooled PS (1.65kW): ~6,500CHF • 9U VME64x complete with local air-cooled PS (3kW): ~8,950CHF • Also available from the Electronics Pool • Single point of contact: Gilbert Dumont EP-ESS • Web site: www.cern.ch/ESS/crateProject/

  4. Hardware - VMEbus processors • Technical specifications of current Pool standard SBCs Cost: CHF 5000 Rental: CHF 106 / month Inventory: 8 Rental: CHF 220 / month Inventory: 39

  5. Hardware - VMEbus interfaces Cost: CHF 8000 Rental: CHF 42 / month Inventory: 21

  6. Operating system support • Linux • EP/ESS provides network booting for VP-110 • Current version: CERN RH 7.3.2 (2.4.18) • Many powerful libraries and drivers available (also for desktop PCs) • Not real time • LynxOS • EP/ESS provides network booting for RIO8062 • Current version: 3.0.1 (frozen since 2000) • Libraries (e.g. for VMEbus access) available from past projects • Real time features • The latest version of Lynx can run Linux binaries. Not (yet) available from EP/ESS

  7. Low Level S/W Under Low level S/W we understand libraries and drivers providing generic services to the higher levels. Libraries and drivers for other I/O channels (Ethernet, SCSI, EIDE, RS232, USB, etc.) come with the operating system or can be found in the public domain

  8. Middle level S/W Under middle level S/W we understand libraries and drivers for specific electronics modules like front end modules or interfaces. Some examples of existing packages: • There also exist libraries (C or LabView) for different front-end modules from different sources including the El. Pool but: • They are not necessarily compatible with the supported VMEbus interfaces • They are not kept in a central place • Documentation is often missing

  9. High level S/W • High level S/W such as DAQ application code, controllers, GUIs, monitoring environments or data recording is not provided by EP/ESS • In the past this level was provided by generic DAQ systems such as CASCADQ • Recently the DATE DAQ system of ALICE has been used successfully by the HARP experiment

  10. Other services • Consultation • Choosing the right H/W and S/W for your DAQ problem • PCI and VMEbus trouble shooting • Powerful bus analyzers available from the El. Pool • Expertise with bus protocols • Testing • Test benches for e.g. TTC or front end modules • Logistics • Handling of purchase and repair of certain electronics modules • Evaluations

  11. Possibilities • Training • Informal courses on how to use VMEbus, front-end modules, etc. • Web based self training • PC based DAQ systems • Should the El. Pool offer PCs • Should the El. Pool offer commercial PCI front-end cards • Should the ESS get involved in the design of front-end PCI cards
