Accelerator R D for Future Neutrino Projects International

Accelerator R&D for Future Neutrino Projects • International context • Current activities in the UK • Plans for the future • Conclusions

International context • Focus here on post-T 2 K, NOνA facilities • Aims driven by CERN SG: “…. . studies of the scientific case for future neutrino facilities and the R&D into associated technologies are required to be in a position to define the optimal neutrino programme based on the information available in around 2012; Council will play an active role in promoting a coordinated European participation in a global neutrino programme” • Within Europe, being done by EUROnu: - FP 7 Design Study - 15 partners, 6 from UK - coordinated by STFC - 13. 5 M€ total budget - runs 1 st September 08 to 31 st August 12 - part of CERN strategy - see http: //www. euronu. org

EUROnu Neutrino Factory CERN to Frejus SB Higher Q isotope Beta Beam + detectors & physics Main objective: “cost” & performance comparison for SG

IDS-NF • International activities. . . . International Design Study for the Neutrino Factory • Aims: IDR ~2010; RDR ~2012 Executive Blondel § Design of accelerator and detector(s) Kuno § Physics performance Zisman § Cost and schedule Long Accelerator Medahi Mori § “Risk” • Chaired by Ken Long • EUROnu – most of EU contribution Berg Prior Detector Bross Cervera Mondal Soler Physics Donini Huber Pascoli Winter Yasuda

NF Collaboration

UK Activities • Fully integrated with IDS-NF and EUROnu • Generic nature of activities exploited for funding Targets Overall conceptual design FETS RF MICE EMMA

Front End Test Stand • Very important section of all high power (>1 MW) drivers Plus associated diagnostic devices Being built by collaboration of: Imperial College STFC Warwick UBC, Spain Important for: Neutrino Factory ISIS upgrades other high power projects SLHC

Front End Test Stand

MICE • Muon Ionisation Cooling Experiment • Crucial engineering demo of cooling for NF and Muon Collider • Under construction in R 5. 2 at RAL • International collaboration: 140 people, 31 institutes, 8 countries Cooling cells PID Tracking detectors

MICE • Status – beam & detectors: - beamline working - PID detectors working - muons seen - target issues being dealt with - hall far advanced - trackers – tested with cosmics • Status – cooling cells – only 1 funded - magnets: under construction - RF: under construction - LH 2 absorbers: 1 built • First demo of cooling: 2010/11

EMMA • Model of muon FFAG accelerator(s) in NF – v. imp. R&D project • Proof-of-principle non-scaling FFAG in BASROC/CONFORM: - proton & light ion cancer therapy - ADSR - muon production for slow muons - etc • Under construction at Daresbury, use ALICE as injector • Funded (mainly) by EPSRC - via BT fund • Well advanced • First beam ~December 09 • Parameters: - electrons, 10 -20 Me. V - 42 cells, 40 cm long - 16. 5 m circumference - 1. 3 GHz RF

Plans • UKNF & MICE funding ring-fenced until March 2012 • Funding through other sources (e. g. ASTe. C) subject to review • Hope: main UK activities converged by then

Plans • UKNF & MICE funding ring-fenced until March 2012 • Funding through other sources (e. g. ASTe. C) subject to review • Hope: main UK activities converged by then • SG 2012 deadline may slip: § LHC delay § world-wide funding means some neutrino work delayed • Post-SG review: work depends on outcome • UK should play a major role, whatever the outcome § building on skills developed § “ “ investment already made § “ “ other possibly developments, e. g. ISIS upgrade • Of course, would like to host a Neutrino Factory

Plans

Conclusions • UK playing v. important role in future neutrino projects • Leading Neutrino Factory accelerator R&D • Exploited various funding sources, including EC • Created KE possibilities • Targeting SG 2012 deadline • Working with SG and SPC neutrino panel § explore increase in CERN resources to EUROnu § determine future neutrino strategy • Still hope to host a Neutrino Factory!
