Outline: 

Outline Introduction i.e. what has happened since last year European feasibility study Proton driver superbeam developments Target Pion collection Muon front-end Muon acceleration ……..with thanks to many people from whom I’ve stolen transparencies!

Introduction: 

Introduction Last year: “…..or the art of [talking] for half an hour about nothing!” cut backs at CERN due to LHC largely not replaced by other labs general lack of funding This year: some signs of improvement: funding from EC FP6 + ISTC uplift in (at least) one country more positive noises from CERN management future proposals to FP6/7 work still being done………..

CARE: 

CARE European Commission 6th Framework Programme: EC has defined various actions to fund many only for specific thematic priorities made substantial funds available – 17.5B€! some actions possible for PP  ESGARD Coordinated a proposal against Integrating Activities  Coordinated Accelerator Research in Europe Exploited two activities: - Networking Activities  BENE - Joint Research Activities  HIPPI

CARE: 

CARE 30% ~.7M€ 30% ~0.3M€ 30% ~0.45M€ 90% 3.6M€ 90% 3.6M€ 25% ~1M€ 65% ~5M€

Other Possible FP6 Actions: 

Other Possible FP6 Actions Design Studies: - 1st round (March 2004): EUROTeV EURISOL - 2nd round ( ): NuFactDS New JRAs under CARE New and Emerging Science and Technology  both discussed later

UK Funding Uplift: 

UK Funding Uplift From UK Gov, mainly due to initiative started by Ken Peach Good news: £21M from PPARC Bad news: LC beam delivery: £9M Cockcroft Institute: £7M Oxford/RH Centre: £2M UKNF: £2M MICE: £1M PPARC £7.5M OST CCLRC Cockcroft Institute:  Discussed later & WG3

European Feasibility Study: 

European Feasibility Study CERN Yellow Report Published 2004: “ECFA/CERN Studies of a European Neutrino Factory Complex”, CERN-2004-002 Chapter on the machine  European Feasibility Study

European Feasibility Study: 

European Feasibility Study

Proton Driver: 

Proton Driver CERN proton driver: SPL Number of changes: politically technically See Haseroth WG3

SPL: 

SPL CERN proton complex increase in protons ultimate L for LHC LHC L upgrade SB to Frejus driver for EURISOL/BB driver for NF

SPL R&D: 

SPL R&D Collaboration/funding: HIPPI: CARE JRA - R&D of the technology for high intensity pulsed proton linear accelerators up to an energy of 200 MeV - 9 labs - 11.1M€ + 3.6M€ (EC) for 5 years (2004-2008) IPHI collaboration: - 3 MeV RFQ ISTC: - DTL with magnetic focusing (3-40 MeV) - DTL with focusing by RF quadrupoles (DTL-RFQ) (3-40 MeV) - Coupled Cavity DTL (40-100 MeV) - $1550 total - all prototypes delivered by summer 2006

SPL R&D: 

SPL R&D 3 MeV test stand

RAL Test Stand: 

RAL Test Stand “5MW” test stand also planned at RAL Builds on existing test stand for current ISIS upgrade Work done for the ESS Main aim is a further ISIS upgrade Directly relevant to Neutrino Factory Complementary to CERN: - different chopper, frequency, etc - more generic Also participating in HIPPI Close collaboration with CERN developing Beam >2007 See Findlay WG3

Target Studies: 

Target Studies Three programmes: Shock studies of solid targets TT2A experiment HARP See Fabich/Catanesi Plenary Kirk/Bennett WG3

Shock Studies: 

Shock Studies Electron beam tests: Electron beam welding machine Only realistic possibility for lifetime test Correct energy density Only surface effect First test done Foil

Shock Studies: 

Shock Studies Second test under consideration Improved experimental setup & diagnostics Results also relevant to T2K

Shock Studies: 

Shock Studies Proton beam tests: Correct energy density available from PS & at ISOLDE Lifetime tests difficult PS will be used for mercury Solid target tests already done at ISOLDE Further tests planned, upgraded instrumentation Also relevant to T2K and CNGS

HARP: 

HARP Precise measurement of for hadrons Input for: - Neutrino Factory & superbeam - atmospheric neutrino flux - hadron production models - MiniBooNE, K2K, LSND experiments Data taking in 2001 and 2002 420M physics triggers, 1.5 to 15 GeV/c, many targets Since then: understanding detector First physics distributions: winter conferences 2004 Latest results: this week………..

Pion Collection - Horns: 

Pion Collection - Horns Baseline collector in CERN layout: horn Standard for conventional neutrino beams Two horns required to achieve focussing needed for the Neutrino Factory See Fabich WG3

Horns: 

Horns Three main issues being studied: - lifetime due to pulsing: 300/600kA at 50Hz - heating/lifetime due to beam - optimisation of parameters for physics

Muon Front-end: 

Muon Front-end CERN “baseline”: all 88MHz linear channel target and horn 15 m decay channel 7.2 m phase rotation cooling (6.4 m/cell) Basically unchanged for 2 years

RAL Front-end Studies: 

RAL Front-end Studies Two front-ends being studied at RAL: - inverse phase rotation chicane - cooling ring Both currently being optimised (pre-GRID!)

Funnelling: 

Funnelling Split proton beam on to “4” targets + horns “Funnel” pions into same decay channel FODO focussing using quads, rather solenoid focussing Pions Muons

Front-end R&D: 

Front-end R&D Contributions to three projects: - MuScat - MuCool - MICE Two others in Europe: - Frictional cooling - Laser ionisation of muonium

MuScat: 

MuScat Measurement of muon MCS as input to - cooling simulations - MICE - Geant Two data-taking runs at TRIUMF – 2000 & 2003 Data analysis taken longer than expected(!): - high precision experiment - small fractions of a few people First results this week See Murray Plenary

MICE: 

MICE European contributions Beamline and infrastructure: UK, Switzerland Tracking detectors: Italy, Switzerland, UK Particle-id detectors: Belgium, Italy Coils: Italy, UK RF-power: Switzerland, UK Magnetic field measurements: Netherlands Software: Italy, Switzerland, UK

Muon Acceleration: 

Muon Acceleration Some activity on RLAs: - at CERN some time ago - Saclay more recently More recently, much activity on FFAGs: - Saclay: beam dynamics studies - CERN: development of FFAG simulations beam dynamics and lattices studies - RAL: studies towards an isochronous, 16 turn, 8-20 GeV FFAG See Meot WG3

Conclusions: 

Conclusions Financial situation has improved Hopefully, this will continue! Focus on a number of projects to attract more people Proton driver: - very healthy - two test stands under development Target and collection: - TT2A - solid target shock studies - tests/simulations of horns - First HARP results soon Front-end: - First MuScat results - MICE progressing well Acceleration: - Focus on e-model FFAG
