Definition of the external interfaces
Technical interfaces: limit of the responsibility
Functional interfaces: integration success and global performances achievement
Definition of the internal interfaces
Elliptical cavity interfaces
PBS
Unavoidable contraints
International collaboration: multilabs contributions (ESS, CEA, IPNO, LASA,
STFC) for interdependant components required to be very formal
Complex technical system
Multi-site
ESS Specific requirements in terms of massive COTS procurements (pumps, valves…)
CEA Saclay/ESSI Project| 8 Feb16 | PAGE 3

Mid-Beta Elliptical Cavities
CEA to provide to ESS for LASA interface drawings to be approved by ESS
High-Beta Elliptical Cavities
CEA to provide to ESS for STFC interface drawings to be validated by ESS
Vacuum interfaces: definition under ESS responsibility
Standardization of gaskets?
Standardization of type of valves?
Standardization of type of pumping system equipment?
He cryogenic interfaces
Lessons learnt from demonstrators for design simplification? (flexible parts, number of weldings vs complex geometry…)
RF line interfaces
Handling and Accelerator building interfaces
Alignment interfaces
Electrical interfaces
Test stand interfaces
No interface with Control System
