1. Forward arm concepts for A-A running with the EIC detector S. Manly University of Rochester EIC workshop BNL, Sept. 19, 2002

2. v 2 vs.  and energy Preliminary v 2 200 Final v 2 130 PHOBOS Au-Au 130 GeV result: nucl-ex/0205021, submitted to PRL v2v2  200 130 ~190

3. EIC detector from white paper

4.  =2.1  =2.8

5. Coverage one wants: Phobos coverage out to roughly  =5.4

6. EIC detector from white paper

7. TPC’s Extend coil Remove 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

8. Tracking with p determination and PID to  3.8

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