Exact capabilities of PS and Neutrino facility remain to be determined/confirmed: PS beam tests PSNF Simulations (FLUKA)

In any case a design should be based on more than maximum capabilities, even if they would be beyond the present PS capabilities

Present Status A partial feasibility study, addressing the most critical

issues, was made and results have been reported to the CERN management

The collaboration memorandum was discussed in the CERN SPSC in April CERN has shown a genuine interest, but is awaiting a

formal proposal to be evaluated Presently the potential issue for the near detector

location (B181) and the present occupation of the neutrino pit and main floor is being addressed.

The existing rough cost estimate should not be used, but a complete conceptual/technical design study should be made instead (no green light) Complete and realistic cost estimate Possible project planning

What are the experimental requirements Proton request based on 80’s production yields:

2.5x1020 for νμ mode used until now in memorandum, presentations and calculations

7.5x1020 for νμ mode to be added ??? Correct productions yields can only be determined

when final design of target and horn are made What is the realistic time line for the

preparation of the experiment ? Transport and re-commissioning of ICARUS Design, construction and commissioning of near

detector Other time constraints will/might come from the

reconstruction of the PSNFInformal Get Together LArTPC@PSNF,
