6. identify answers (and dates) to be given during 2005


● Future neutrino facilities offer great promise for fundamental discoveries (such as CP violation) in neutrino physics, and a post-LHC construction window may exist for a facility to be sited at CERN.

● CERN should arrange a budget and personnel to enhance its participation in further developing the physics case and the technologies necessary for the realization of such facilities. This would allow CERN to play a significant role in such projects wherever they are sited.

● A high-power proton driver is a main building block of future projects, and is therefore required.

● A direct superbeam from a 2.2 GeV SPL alone does not appear to be the most attractive option for a future CERN neutrino experiment as it does not produce a significant advance on T2K.

● We welcome the effort, partly funded by the EU, concerned with the conceptual design of a β-beam. At the same time CERN should support the European neutrino factory initiative in its conceptual design.

SPSC Recommendations (p.63)


Implications of SPSC Villars’s recommendations for the AB department are being sent to the Research Board

Special INTC meeting (Villars – Oct. 2005) new set of recommendations (nuclear physics community)

Creation of an accelerator team to elaborate scenarios

Accelerator studies in the frame of:CARE [EU supported Integrated Activity: “Coordinated Accelerator

Research in Europe” including networks (BENE: “Beams for European Neutrino Experiments”, H3: “High energy, High intensity, High brightness” accelerators) and the Joint Research Activity HIPPI: “High Intensity Pulsed Proton Injectors”]

LHC upgrade studiesEURISOL Design Study [EU supported]

Future of proton accelerators at CERN

LHC will operate until ~ 2020

Consolidation + LHC upgrade

LHC will always be a part-time user of the injector complex

Other physics programmes can be covered if they are compatible with LHC needs. On top of value for science, synergy will be an important parameter.

High energy yield now appears a factor of 2 over low energy, but how much of that kink is real?

Stage 1: 3 MeV test place development and test of linac

equipment, beam characterization

Stage 2: Linac4 New linac replacing the present

injector of the PS Booster (Linac2) Front-end of the future SPL improvement of the beams for

physics (higher performance and easier operation for LHC, ISOLDE etc.)

Stage 3: SPL New injector for the PS, replacing the PS Booster New physics experiments using a high proton flux

improvement of the beams for physics and possibility of new experiments

EURISOL – Multi-MW Target


The CERN Neutrino Factory and Superbeam baseline scenario

1. proton source= either (some version of) SPL (baseline) or RCS

advantages of SPL = better potential to increase powerdisadvantage = need additional accumulator (SB) and compressor (NF) to keep short (3 s or 3 ns ) bunches time structure = 144 bunches at 50Hz operation cost?

2. collector = horn (baseline) or 20T solenoid horn is cheap and disposable. Efficient for single sign, but one sign only. synergy with Superbeam. 50Hz operation is hard

3. RF phase rotation at 88 MHz. Allowed one bunch of muons per bunch of protons. Muon-collider compatible! can this do both signs?

4. there never was an end-to-end simulation, performance was evaluated with interfaces.

in general was very similar to PJK scenario
