Presentation Transcript

  1. Status of Analysis • Fortnightly meetings to discuss physics analysis progress and plans (link) • Meetings are well-attended and foster much lively discussion • All analyses are presented at meetings before publication • Many topics are discussed at meetings, aimed towards completing Monte Carlo analysis in preparation for data taking • Main areas for publication at Step IV are undergoing Monte Carlo-based analysis now

  2. Publications Recent Publications Pending Publications “Particle identification in the low momentum MICE muon beam, to measure its pion contamination” To be submitted to JINST, draft under internal MICE review Confirms the low pion contamination of the MICE beam line “Commissioning of the EMR in MICE Step I” Analysis nearing completion • “Characterisation of the muon beams for the Muon Ionisation Cooling Experiment” • DOI: 10.1140/epjc/s10052-013-2582-8 • European Physical Journal C, October 2013 • Quantified the upstream beam line emittance, momentum and dispersion + manyconference papers and talks

  3. Analysis at Step IV A full and definitive exploration of the ionisation cooling equation + Proof that we can predict it + Proof that we can measure it Depends on upstream beam line (mostly diffuser) Depends on magnetic lattice Ionisation Cooling Multiple scattering ,  depends on D2 selection Depends on material Measure a change in emittance Depends on particle species  backgrounds!

  4. Analysis at Step IV Diffuser EMR SS1 FC SS2 CKOVs 7.5—8m TOF0 TOF1 Tracker planes Absorber TOF2 KL • Step IV.0: MICE Step IV, without magnetic field • Straight track measurements • Alignment of experiment • Confirmation of particle ID • Multiple scattering studies with full/empty absorber, scattering distributions from high-Z material (diffuser)

  5. Analysis at Step IV Diffuser EMR SS1 FC SS2 CKOVs 7.5—8m TOF0 TOF1 Tracker planes Empty Absorber TOF2 KL • Step IV.1: MICE Step IV, with magnetic field, no absorber • Helical tracks • Confirmation of particle ID with full reconstruction of tracks • lattice studies and momentum acceptance • background study • background study • Transmission efficiency of an empty channel • Characterisation of available input emittance via diffuser

  6. Analysis at Step IV Diffuser EMR SS1 FC SS2 CKOVs 7.5—8m TOF0 TOF1 Tracker planes Absorber TOF2 KL • Step IV.2a: MICE Step IV, with magnetic field and LH2 absorber • study for liquid hydrogen as a function of • Transmission efficiency of Step IV • study as a function of and input emittance • Concludes ionisation cooling without reacceleration in liquid hydrogen • Step IV.2b: Solid absorber measurements • Repeat liquid hydrogen analyses for different low-Z absorbers (e.g. LiH) • Equilibrium emittance found for each material • Concludes ionisation cooling without reacceleration in low-Z materials
