  1. Outline • SPS North Area – H8 beam line • PS East Area Test Beams at CERN for ν-Detector R&D Neu2012 Meeting CERN – September 27-28, 2010 I. Efthymiopoulos – CERN EDMS No:

  2. Test Beams at CERN for Detector R&D SPS North Area • The proton beam (400 GeV/c) from SPS is slowly extracted to the North Area at LSS2 • The extracted beam is transported in the TT20 tunnel • 11% slope to arrive into TCC2 – then horizontal ; ~10m underground

  3. Test Beams at CERN for Detector R&D SPS North Area • Particle types: electrons, hadrons, muons • Intensity : max 12 × 108 particles/spill • Flat top : 49 sec • Cycle : 16.8 49s • H2, H4, H8 : 10  400(450) GeV/c • H8 : attenuated proton beam • H2 and H8 : have a VLE branch  beams 1-9 GeV/c • H6 up to 200 GeV/c

  4. Test Beams at CERN for Detector R&D

  5. Test Beams at CERN for Detector R&D PS East Area • Secondary beam : 1  15 GeV/c • Particle types: electrons, hadrons, muons • Intensity : 103- 104, max 1  2 × 106 particles/spill • Spill structure: 400 ms length, 1 spill/33.6 s (PS sc)

  7. Test beam Magnets CERN-PH magnet stock (partly up-to-date): http://ph-dep-dt1.web.cern.ch/ph-dep-dt1/Organization/MM/Magnet-List-2007.pdf See also: http://doc.cern.ch/archive/electronic/cern/preprints/open/open-2004-003.pdf Presently installed test beam magnets: • PS east hall: • TPC-90 magnet (last used by HARP), solenoid diam. 90 cm, 224 cm long, 0.7 T (~1.3 T in pulsed mode). • EHN1, H2 beam line: • M1 magnet, superconducting, large dipole, 82 cm gap, 1.4 m diameter, Field 3T,used by CMS • MNP22A, C-shaped classical dipole, 50 cm gap, 1 m width, 1 m depth, 1.37 T (presently 0.7 T)

  8. beam B field 3T Helmholtz magnet Test beam Magnets H2 beam line magnet - CMS • Proposed for RF test area for NF cavities http://ieeexplore.ieee.org/iel5/20/22845/01060951.pdf?tp=&isnumber=&arnumber=1060951

  9. A Low Energy Muon beam in H8 line Beam design principle

  10. A Low Energy Muon beam in H8 line Issues to optimize • Energy of incoming secondary beam and target material • Overall length of the tertiary beam line • Position of the detector wrt the muon background from the secondary beam • Typically 1% of icomingmuon flux in a 10x10cm2 area on the beam axis AND another 1% in a 1m2 area outside • Expected (~measured) pion rate: ~1kHz @ 1 GeV/c • To be studied as part of the AIDA project

  11. A Low Energy Muon beam in H8 line Area Layout – EHN1 building Detector Area Secondary Target Experimental Magnet
