  1. 1/13 Analysis overview & “The Missing Physics” V. Blackmore CM38 23rd February 2014

  2. 2/13 Purpose of this talk... • You will hear about • Our (physics) readiness for carrying out Step IV • Our (physics) preparations for Step V or Step VI • This talk is what you will not hear about.

  3. 3/13 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. 4/13 Analysis at Step IV famous last words! Depends on upstream beam line (mostly diffuser) Depends on magnetic lattice “Sounds simple enough...” Ionisation Cooling Multiple scattering ,  depends on D2 selection Depends on material Measure a change in emittance Depends on particle species  backgrounds!

  5. Presented as part of the “analysis wishlist” discussion on Sunday 5/13 Diffuser Step IV Operating States EMR SS1 FC SS2 CKOVs 7.5—8m TOF0 TOF1 Tracker planes Absorber TOF2 KL No fields No/empty absorber With absorber No fields, no absorber No fields, LH2 No fields, solid absorber Fields, no absorber Fields, LH2 Fields, solid absorber LiH Fields (Flip/Solenoid mode) Plastic, Al,... LiH wedge Noble Goal: Always have a Monte Carlo beforetaking data!

  6. Presented as part of the “analysis wishlist” discussion on Sunday 6/13 indicates “influences” NB: Each consists of many sub-analyses. PID and straight track reconstruction Detector alignment Multiple scattering: high-Z Multiple scattering: low-Z Background study No fields, no absorber No fields, LH2 No fields, solid absorber

  7. Presented as part of the “analysis wishlist” discussion on Sunday 7/13 indicates “influences” NB: Each consists of many sub-analyses. PID and straight track reconstruction Detector alignment Multiple scattering: high-Z Multiple scattering: low-Z Background study No fields, no absorber No fields, LH2 No fields, solid absorber Full track reconstruction & PID Measure of input beams Fields, no absorber Characterise lattice

  8. Presented as part of the “analysis wishlist” discussion on Sunday 8/13 PID and straight track reconstruction Repeat for each type of absorber: liquid, disc or wedge Detector alignment Multiple scattering: high-Z Multiple scattering: low-Z Multiple scattering: low-Z Background study Background study No fields, no absorber No fields, LH2 No fields, solid absorber Full track reconstruction & PID Heating term Measure of input beams Fields, no absorber Fields, LH2 Fields, solid absorber Characterise lattice

  9.

  10. Presented as part of the “analysis wishlist” discussion on Sunday 10/13 PID and straight track reconstruction Repeat for each type of absorber: liquid, disc or wedge Detector alignment Multiple scattering: high-Z Multiple scattering: low-Z Multiple scattering: low-Z Background study Background study No fields, no absorber No fields, LH2 No fields, solid absorber Cooling term Full track reconstruction & PID Heating term Measure of input beams Fields, no absorber Fields, LH2 Fields, solid absorber Characterise lattice Background study Equilibrium emittance & ionisation cooling

  11. 11/13 What you won’t hear about today...? PID and straight track reconstruction Repeat for each type of absorber: liquid, disc or wedge Detector alignment Multiple scattering: high-Z Multiple scattering: low-Z Multiple scattering: low-Z Background study Background study No fields, no absorber No fields, LH2 No fields, solid absorber Cooling term Full track reconstruction & PID Heating term Measure of input beams Fields, no absorber Fields, LH2 Fields, solid absorber Characterise lattice Background study Equilibrium emittance & ionisation cooling

  12. Presented as part of the “analysis wishlist” discussion on Sunday 12/13 Progress (MC only): “Circle of Glory” PID and straight track reconstruction The proportion of green is a “guesstimate” “Circle of Hope” Detector alignment “Circle of Gloom” Multiple scattering: high-Z Multiple scattering: low-Z Multiple scattering: low-Z Background study Background study No fields, no absorber No fields, LH2 No fields, solid absorber Heating term Cooling term Full track reconstruction & PID + all of this influences Step V, Step VI... Measure of input beams Fields, no absorber Fields, LH2 Fields, solid absorber Characterise lattice Background study Equilibrium emittance & ionisation cooling
