A Detector for Forward Physics at eRHIC: Feasibility Study

Abstract

The eRHIC facility planned for the Brookhaven National Laboratory will allow detailed studies of the strong hadronic interactions. Among the exciting research topics discussed are the pursuit of the Color Glass Condensate, the three dimensional scan of nucleons and nuclei, and the solution to the mystery of how the proton spin is built up from its constituents. This document describes a detector optimized for forward physics at such an accelerator. The experience gained at HERA allows for the design of a detector which will give optimal performance in the kinematic regions of highest priority, the small and large $x$ regimes. Detailed simulations of the detector were carried out, and performance results for structure function measurements are presented.
