Coverage one wants: Phobos coverage out to roughly =5.4

TPC’s
Extend coilRemove lepton side endcap emcal
PID
Keep hadron side flux return the same thickness
Add si ring tracker to cover intermediate region
Offset collision point
Mods to EIC detector to optimize for AA forward region

For coverage to higher h, put annular rings (a la PHOBOS or current white paper concept?) out to z=9m

Interaction Point
PHOBOS Octagon, vertex and ring detectors
Ring counter
Change ring design to groups of three annular rings with smaller pad size so one can form three point tracklets to cut down on background
