HL-LHC Hollow Electron Lens (production) kick-off meeting
The scope of the meeting is to:
- validate the HEL functional specifications,
- delineate a HEL reference design (as a starting point to organise the work),
- describe the work break-down structure and responsibilities,
- give a first estimate on budget/resources,
- define what has to be done at CERN (and with what additional resources from in-kinds) and what can be outsourced including validation measurements, assembly and testing.

Technical design as seen by equipment owners/responsible and first estimates on resources
• What needs to be done : translation of FS into design main parameters
• What needs to be done in-house and what can be done as in-kind
• First estimate of resources required at CERN and from in-kind contributors (PJAS coming at CERN, profile to be specified), to be validated at a later TCC (in May/June)-
