HI-ECN3 Target Complex Infrastructure Workshop

Thursday 12 Jun 2025, 08:45 → 17:00 Europe/Zurich

30/7-018 - Kjell Johnsen Auditorium (CERN)

Fernando Baltasar Dos Santos Pedrosa (CERN), Jean-Louis Grenard (CERN)

Objectives of this workshop:

• Ensure all requirements are understood
• To understand studies progress by the different parties
• Ensure sufficient spaces are reserved within the target complex
• Ensure interfaces between systems are defined

Mainly we will focus on the new target complex service building but we will include specific aspect linked to the rooting of utilities from/to ECN3/TCC8

Planning, Budget and Resources won't be discussed during this Workshop.
