May 2008 Review Subsystem Review

• still need date (probably middle to end of May), charge, names of reviewers, etc. from 12GeV Project office
• need pre-brief materials a few weeks before review
• both the Electronics and DAQ groups are working on docs suitable for pre-brief materials
• trigger group (aka Dave D) will generate pre-brief materials for trigger system design
• need to complete tests and freeze development a few weeks before pre-brief materials are due
• need last few weeks before review for practice talks, revision of pre-brief materials, etc.
• May milestones in Online Major Milestones are still acceptable/possible
• Chris/Fernando are nearly done with electronics drawings, some work needed for DAQ and networks sections
• crate-sum demo should be ready for review
• general agreement that 200 kHz triggering demo will (might?) happen by the review
• prototype TI board should be back in two weeks or so

Trigger Studies

Alex S presented latest results from his MC study of triggering in Hall D. MUCH discussion followed, and it was clear that Alex needs to make a complete presentation in a separate meeting devoted to this topic. He will collect a complete set of plots, starting from ground zero, and present them in the next week or two.

• studied hadronic backgrounds, via Eugene's Pythia++, and E-M background, via Geant3
• included pileup in 100 ns gate
• looked at FCAL and BCAL energy sums, and TOF multiplicities
• used Richard's full beam simulation, including complete bremstrahlung spectrum, collimator, beam pipe, etc.
• more at the dedicated meeting...
