8. FIT R&D Plan & Q for Simulation
Follow up on previous BNL R&D
& study zigzag-strip readout to reduce
# of readout strips & consequently
cost of electronics for large tracker
Questions:
What spatial resolution would be
needed for an EIC tracker?
Can it be different for  and ?
What is the expected occupancy?
What readout cell size would be needed?
