Markus Joos, EP-ESS 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

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

Markus Joos, EP-ESS 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. Type of modulePCVP-110RIO2 TTCviN/AYesNo ? S-Link (AMCC)Yes S-Link 64-bit PCIYesNo CORBOYes ALICE FEDCN/AYesNo ? 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 Some examples of existing packages:

Markus Joos, EP-ESS 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

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

Markus Joos, EP-ESS 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
