hardware (Steve, Yung)

- Physics conditions & Background.

- expected multiplicities, particle mix

- beam extensions

- rates (crossings/ Interactions...)

 

- Criteria, Quantify those

- see attached prelim list

- +position determination capabilities/possibilities

 

- Simulation results

- detector response (dynamic range

- segmentation. How much is needed for a minimum configuration.

- dn/deta

- dn/dM

- central vs peripheral

- background for other detectors (identified as of now, other concerns?)

 

- Hardware.

- performance of Si-det. noise/resolution

electronics, cabling

- performance of Scint.. noise, signal,..

- built with expansion possibilities.

- rates capabilities, pile-up?

- HV systems.

- triggering schemes

 

- Physical constraints

- beam-pipe size, material positioning.

- regions free of material (magnets, beam-beam counters..)

- pivot, platform design near pivot.

 

- Workplan

- additional R&D needed; identify, time for decisions..

- task division

- hardware/software/electronics

- timetable, costs

- workplan, MOU's
