  2. Final Differential Cross-Section Extrapolation to t = 0: B = 20.1 GeV -2 Exponential slope B = 23.6 GeV -2 Good agreement with the measurement at |t| > 0.36 GeV2 [EPL 95 (2011) 41001] Total elastic cross-section: Karsten Eggert–

  3. Closest approach at 90 m run (~4.8 s) Karsten Eggert–

  4. Correlation of the two protons Last run ( ~10 s ) t min ~ 1.5 10 -2 GeV 2 Int. luminosity: 1.9 mbarn -1 26 k elastic events This run( ~4.5 s ) t min ~ 4 10 -3 GeV 2 Karsten Eggert–

  5. Run with b* = 90 m today (18. Oct. 2011) • Beam configuration: • 10 – 15 minibunches: 1 x 10 10 p/bunch (pile-up 0.005) • TOTEM configuration: • RP @ 5 s • All detectors T1, T2 and RP operational • Trigger: T1, T2 or RP • bunch crossings to evaluate trigger efficiency • Running time at least 4 hours • Physics goals • Luminosity indep. measurement of stot • Study of diffraction (SD and DPE) • t - distribution of elast. scatt., DPE and SD |t| GeV2 Karsten Eggert–
