Presentation Transcript

  1. ωa-Europa status Europa

  2. Overview • Recon west clustering, T-method and energy binned • Time synchronisation checked independently • Absolute energy calibration cross check (won’t be ready for 60hr unblinding) • See doc-db15355 for most recent update

  3. Support notes • Notes to be completed before 60hr unblinding: • Time synchronisation (14851) • Double pulse (13978, update to follow) • Lost muon (internal review) • Tracking (internal review) • Gain correction • Fitting procedure (T-method and energy weighted)

  4. Fitting procedure • Corrections: • Gain - ‘official’ procedure • Pileup - now including triples • R-wave - shifting arrival time by random number 0 < 151ns (after pileup) • The fit model includes (sequentially): • Radial CBO • Vertical CBO • Lost muon • Varying CBO • To be added: • Phase and Asymmetry CBO terms

  5. Concerns/timeline • All of the group currently either working on laser analyses (double pulse) or tracking analyses (pitch, E-field) • Also responsible for these systems at start of run 2 • Energy weighted analysis recently restarted (original student finished), could be tight for time • Weekly meetings every Friday morning, on track for completed analyses and notes by end of 3rd week of Jan (25th)
