Forward arm concepts for A-A running with the EIC detector
S. Manly
University of Rochester
EIC workshop
BNL, Sept. 19, 2002
v2 vs. and energy
Preliminary v2200
Final v2130
PHOBOS Au-Au
130 GeV result: nucl-ex/0205021, submitted to PRL
v 2
200 130
<Npart>~190
EIC detector from white paper
EIC detector from white paper
=2.1
=2.8
Coverage one wants: Phobos coverage out to roughly =5.4
EIC detector from white paper
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
Tracking with p determination and PID to 3.8
For coverage to higher h, put annular rings (a la PHOBOS or current white paper concept?) out to z=9m
-1.1m

-2.3m
5.0m
-5.0m

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
