  1. We convinced ourselves that there is an inversion in X • monitor: bias in slab-x (beam centered on slab x =4)  x_coord=+5cm • indeed in G4MICE it SHOULD be -5cm, according to coordinate convention X-FLIP in TOF1 (TOF0) (TOF2 also?)

  2. b) Comparison MC / DATA (Mark R.) NuFact10 - Mumbai

  3. c) Common Sense … Data Phase Space and Momentum Reconstruction: Q789 scan runs NO survey corrections MC Q789 = -30% NuFact10 - Mumbai

  4. Data Phase Space and Momentum Reconstruction: Q789 scan runs NO survey corrections MC Q789 = -20% NuFact10 - Mumbai

  5. DX / DY survey correction ADDED Q789 = -30% NuFact10 - Mumbai

  6. DX / DY survey correction ADDED Q789 = -20% NuFact10 - Mumbai

  7. My Task after the quick Oxford meeting was To produce a large sample for Mark’s work Beam after D2 to be propagated in G4MICE Implementation easy: - I can run a new optics in 5 min. Result nearly fine: - it stopped before completing (probably due to batch time?) - produce ¼ of the sample requested - I need feedback (love or loath?) - something more? Yes, I already know it: you want output at US-D2 don’t you?

  8. Beam composition after D2 – chosen Momentum Acceptance [226-250] m [226 – 250] p [226 – 250] p/m [226-250] = 1.1%

  9. Stealing Ideas … fast-sim for the BL • Confession: • the original idea is by Chris Rogers • I think it’s a good idea (I made a test on G4Beamline) • Important to perform fast optimization • Atonement: • I would like to work on it and help make it real • Mimic a beam line element with a Matrix (Lin. Approx.) • Four “probe particles” used to explore the element (e.g. a triplet), upstream to downstream  • Infer the Matrix reproducing the same result a) For ONE central momentum b) With Momentum Interpolation (x03,y03) (x13,y13) (x02,y02) (x12,y12) (x11,y11) (x00,y00) (x10,y10) (x01,y01)

  10. DownStream Ph Space for a TRIPLET with Pcent=238 ±23.8 MeV/c NO INTERPOLATION
