PPT Slide

Data Taking

• No special conditions required

• Read out Roman Pot detectors for all events

(can’t miss )

• A few dedicated global triggers for diffractive

jets, double pomeron, and elastic events

• Use fiber tracker trigger board -- select

x , |t| ranges at L1, readout DO standard

• Reject fakes from multiple interactions

(Ex. SD + dijet) using L0 timing, silicon

tracker, longitudinal momentum conservation,

and scintillation timing

• Obtain large samples (for 1 fb-1):
  ~ 1K diffractive W bosons
  
  ~ 3K hard double pomeron
  ~500K diffractive dijets

with minimal impact on standard DO
