Cafe neutrino meeting minutes (02/01/10)
Present: E. Benedetto, A. Blondel, F. Dufour, I. Efthymiopoulos, R. Gabory, C. Hansen, G. Prior, E. Wildner

Agenda:

News from Chamonix workshop (R. Garoby):

Presentations mostly on LHC upgrade scenarios. Seems that there is no strong statement on what should be done in the future which can be worrying for the neutrino facilities community. But they want to come with some decision in May. On the injector side an internal proposal for further upgrade of the current booster and PS is being pushed forward with preliminary numbers that may look over optimistic. From ATLAS channel is seems that the next two years will be at 7 TeV CM followed by a long shutdown to replace the splices. So won't go to 14 TeV CM before 2012. Plans for the integrated luminosity is 1 fb^-1 for 2010. On the other hand, there is still some potential to have a neutrino physics program based on SPL. Will need to fight for it. On the BB side, don't know which machine to calculate and with very little manpower. If the neutrino facility design study continues until 2012, there is still some potential to propose a coherent program. Difficult to defend PS2 in front of a whole PS+SPS complex and PS2 does not seem to be linked to a machine complex. But if SPL stays open in addition to say physics for BB + super-beam, can make a reasonable and perfectly defendable program. Need to revise the different options and work on a scenario that would be fitting at CERN.

Costing workshop at CERN 15-16 March 2010 (I. Efthymiopoulos):
The aim is to come up within EUROnu and IDS to an idea on how to do the costing. Need guide lines on what should be put on the costing. WP management is working on it. Presentations/tutorials by 2-3 persons to explain how to do the cost (theory and practice). Different areas where costing is made will be presented (public, airbus industry, civil engineering industry, CLIC...) and give us some training. The idea is not to put numbers but to see the structure and see how to do a costing. In the future there is a proposal to use some costing tool developed at CERN. If adopted will serve for future costing. The elements to be put in will be decided together. Elena W. is recalling that the costing should be done by the same team for the three proposed facilities in order to evaluate them equally and that this is resource draining so manpower need to be found for that. Every WP will have a representative that will collect the relevant information and set up for each WP the list of items to include in the cost. Options and what to include or not will be defined as well as how to compare cost on equal footing. Errors bars on cost should also be meaningful. Detectors are not directly included, within LAGUNA some cost estimate will be provided but detector technology is not within EUROnu. There is a separate cost for WC, LAr and Scintillators with different areas where the costing is uncertain.
