SPIRAL-2 philosophy : Smoothest beam dynamics (regular FDO lattice, low number of -sections), Modular solution and simple cryostats, Separated vacuum (safety with FP), Warm focusing (easier for alignement), Possibility to insert diagnostics at each period, ease of tuning
Main technical requirements:
Only 2-gap cavities (high q/A acceptance)
Max. accelerating fields 7.8 MV/m
Nominal operation for A/Q between 4 and 8
Design of the post-accelerator

Financial Situation
• Second Pre-Financing has been received and distributed. Third expected next year (no auditing for 3rd year).
• Extension will allow the timely use of all resources• Spending in-line with expectations (95%)• Slight overspending in Personnel compensated by
under spending in T&S and Consumables
![Page 15: EURISOL DS : Status and Future Yorick Blumenfeld IPN Orsay We acknowledge the financial support of the European Community under the FP6 Research Infrastructure](https://reader036.vdocuments.net/reader036/viewer/2022070305/5514cb78550346b0478b4cae/html5/thumbnails/15.jpg)
Proposal for the Future of EURISOL
• EURISOL has made use of EC instruments: 5th framework RTD and 6th framework DS.
• Major advances have been achieved and a large community with varied technical expertise has developed and must continue to be nurtured
• Full engineering report necessary before Pre-construction phase: No (evident) EC instrument for funding.
• We (the EURISOL DS MB) propose to form a EURISOL collaboration consisting of laboratories interested in participating in the continuing effort.
![Page 16: EURISOL DS : Status and Future Yorick Blumenfeld IPN Orsay We acknowledge the financial support of the European Community under the FP6 Research Infrastructure](https://reader036.vdocuments.net/reader036/viewer/2022070305/5514cb78550346b0478b4cae/html5/thumbnails/16.jpg)
Role of the EURISOL Collaboration
• Follow the scientific and policy recommendations of NuPECC
• Promote and Coordinate the R&D to further EURISOL
• Solicit support of the funding agencies, in particular through the NuPNET Eranet, and explore other funding opportunities (EC, intercontinental…)
• Interact with the EC >> entry on the ESFRI list.• Goal : Produce a full engineering report for the
facility
![Page 17: EURISOL DS : Status and Future Yorick Blumenfeld IPN Orsay We acknowledge the financial support of the European Community under the FP6 Research Infrastructure](https://reader036.vdocuments.net/reader036/viewer/2022070305/5514cb78550346b0478b4cae/html5/thumbnails/17.jpg)
Organization of the EURISOL Collaboration
• Collaboration board representing participants >> Elects collaboration chairperson and appoints project leader.
• Project office supported by collaboration fee.
• Engineering work coordinated by project leader and funded by funding agencies (+ other), preferably coordinated by NuPNET.
• Work divided into work packages
