EUROThe European Design Study for a high intensity neutrino oscillation

facility (Rob Edgecock, Mats Lindroos, Marcos

Dracos)

04/10/2007 M. Dracos 2

What is an EU Design Study?

• The 27 European Union member states is in the process of creating a common Research Area with common Research Infrastructure

• The EU funding for research is organized as Frame Work programmers with different components– The FP contributes with 5% to the total national research funding in

Europe– We are presently working within the 6th FP– The Design Studies is one component in the FP and has as objective to

provide first designs for possible common research infrastructure

• The ESFRI (European Strategy Forum on Research Infrastructures, European roadmap for research infrastructures) committee establishes a priority list for new common infrastructure to which the EU is willing to contribute– The Design Studies is the first step in the process to qualify for

financing from the EU for the infrastructure– For the infrastructure to be constructed a member state(s) or an

intergovernmental organization must bid for it and offer an important part of the funding

• International participation is strongly encouraged

Objectives of EURONU DS

• The recent discovery that the neutrino changes type (or flavour) as it travels through space, a phenomenon referred to as neutrino oscillations…

• The implications are far reaching…

• Knowledge of the contribution of neutrinos in these areas needs precise measurements of the parameters governing neutrino oscillations.

• This will require a new high intensity beam-based neutrino oscillation facility in which neutrino beams are generated using new and highly challenging concepts.

• This Design Study will review all three currently accepted methods of realizing this facility (the so-called neutrino Super-Beams, Beta Beams and Neutrino Factories).

• It includes a detailed study of the key technical challenges of the accelerator facilities, of the detector options necessary to measure the neutrino oscillation parameters and a comparison of the physics reach of these facilities.

• The design study will also perform a cost assessment that, coupled with the physics performance, will permit the European research authorities to make a timely decision on the lay-out and construction of the future European neutrino oscillation facility.

Objectives of the tasks

• Management:– Lead and coordinate the DS– Comparison of the three facilities

• Super beam:– Design of target and collector– Beam characteristics for the SPL superbeam– Specifications for the proton driver

• Neutrino factory– Design of muon front end– Design of an acceleration scenario– Develop a conceptual design for proton beam

handling after the primary production target (proton beam dump)

– End-to-end simulation of the neutrino factory complex

Objectives of the tasks

• Beta-beam– Review acceleration scenario for high-Q value

isotopes– Production of beta-beam isotopes with the production

ring concept– Review decay ring design for high-Q value isotopes– Continue R&D on bunching

• Detector task– Study a Magnetized Iron Neutrino Detector– Study a Cerenkov detector – Study a near detector

• Physics task– Study physics performance– Make optimization of the different possible scenarios– Make a comparison
