Meeting minutes
- The project covers completion and integration of the beamline infrastructure required to serve the PUMA experiment, with particularly demanding vacuum requirements compared with other ISOLDE beamlines.
- Remaining installation work is mainly beam instrumentation. Afterwards, vacuum performance and beam transport can be commissioned using an offline source. Full completion is expected in 2027, while first physics operation is foreseen after accelerator operation restarts in 2028.
- For asset accounting, the project should therefore not yet be considered completed. Addition to the asset register should be handled in 2027 once the equipment is ready for use.
- Approximately CHF 1.2–1.3 million has been charged to the project, distributed across many individual costs. The existing work packages and Engineering Change Request (ECR) cost structure should provide the basis for grouping these costs into assets.
- Relevant asset categories include vacuum, beam instrumentation, power converters, cabling/power distribution, and transport/handling. Shared costs such as cabling may need to be allocated separately rather than assigned directly to individual work packages.
- Beam instrumentation can be split between electronic and mechanical assets according to useful life. The roughly CHF 108k diagnostic-box cost should be included within beam instrumentation/mechanics rather than treated as a separate asset.
- Asset-register granularity should primarily reflect differences in useful life and depreciation, rather than reproducing every individual project purchase or component.
- Assets should not be named specifically after PUMA, since the beamline is intended for more general future use. Engineering identifiers such as RC6/RC7 would provide a more useful long-term description.
- Asset accounting follows projects above an approximately CHF 100k threshold and ultimately feeds CERN's financial statements and supports insurance information.
- Other significant ISOLDE consolidation activities may also need to be captured in the asset process, depending on how they are grouped and managed at project/department level.
Action items
- Oliver: Send Sonya Danielle Breslin the Engineering Change Request document/link containing the project cost breakdown.
- Lukas Nies: Check with group/department management how other significant ISOLDE consolidation projects are handled for asset accounting and whether further projects should be reported.
- Lukas Nies / project team: Provide a suitable engineering designation, such as RC6/RC7 where applicable, for the asset descriptions rather than naming them solely after PUMA.
