ALICE, ATLAS, CMS & LHCb Third Joint Workshop on DAQ@LHC

3 Feb 2025, 09:00 → 5 Feb 2025, 21:25 Europe/Zurich

Château de Bossey (20 km from CERN)

The workshop aims at providing a forum to:

• share experiences acquired to date on operating data acquisition systems at the LHC
• exchange ideas, plans and the status of ongoing upgrades in the four experiments 
• build a network across experiments and find commonalities and possible future sharing possibilities
• discuss future plans and discovere the ongoign R&D efforts

 

Registration is free, but participants are requested to register online by the January 10th 2025. Participation is limited to 120 people. Lunches and breaks are included in the registration.

Topics to be covered will include:

• Detector Readout
• Dataflow
• Storage systems
• Systems management
• System control and configuration
• Expert systems
• Information sharing
• Monitoring infrastructure
• Web services
• Trends in software and hardware technologies
