Summary of IAP comments from 2007 EURISOL Town Meeting Sytze Brandenburg, for the IAP

Response to previous report IAP appreciates & acknowledges written response to last year’s report design study initiatives following the comments IAP concerned about issues not addressed

Comments from 2007 meeting coordination & overall progress evident format 2007 town meeting format not appropriate for detailed assessment project progress information website no remedy

Comments from 2007 meeting driver accelerator credible proposal for multiple independent beams good positive progress on prototypes concern: beam losses H- stripping losses heavy ions ‘vacuum’ stripping losses, ECR beam emittance

has been done two weeks ago Comments from 2007 meeting 100 kW targets plan for 100 kW targets appropriate & credible mMW Target fission target based on MAFF-design step towards credibility emphasis on Hg-film target assessment consequences 235U to be evaluated isotopes and intensities licensing independent evaluation of UCx development program has been done two weeks ago

Comments from 2007 meeting beam preparation progress difficult to assess (not evident from the presentations and website) critical issue: gas-filled RFQ-cooler post-accelerator post accelerator continues to be credible good progress on prototyping study stripping option insufficiently advanced concern: study of beam losses by ‘vacuum’ stripping

Comments from 2007 meeting beta beams good progress on radiation issues impact alternative scenarios for production feasibility full-scale LLN-approach to be studied coordination with EURO concern: no strong support from neutrino community

Comments from 2007 meeting radiation safety: several urgent issues: DRL define constraints for estimations propose credible concepts to achieve these limits use GANIL or CERN as guidelines for estimates? not necessary to set up models to determine DRLs evaluate credible environmental & accident consequences propose mitigation schemes explore exposure maintenance personnel exposure, remote handling & nuclear ventilation impacts concern: progress on system integration radiation safety

Comments from 2007 meeting physics and instrumentation updated case and proposed experiments OK document format clear and concise

Comments from 2007 meeting user group not moving towards advocacy role as quickly as expected the progress and goals disappointing to the IAP outreach brochure good start towards outside support

Comments from 2007 meeting site study committee IAP is concerned about the mandate of this sub committee has the charge been adequately defined? EURISOL future the community needs to be informed of project continuity new priorities need to be set so that the EURISOL DS results can be exploited with maximum benefit to the community a transition plan needs to be established & approved
