Description
The long-term upgrade plan for the RHIC facility foresees the addition of a high-energy polarized
electron beam to the existing hadron machine, thus converting RHIC into an
Electron-Ion Collider (eRHIC) with luminosities exceeding $10^{33} cm^{-1} s^{-1}$ [1]. The main
physics topics to
be explored at this new facility are (i) the polarized sea quark and gluon distributions in the
nucleon, (ii) QCD dynamics of the low-x, high density gluon regime, (iii) hadronization and energy
loss in the nuclear medium. A dedicated eRHIC detector,
designed to efficiently register and identify deep inelastic electron scattering (DIS)
processes in a wide range of center-of-mass energies available with the new collider is one
of the key elements of this upgrade. The detector and interaction region design will be shown,
technology choices discussed, and the first physics simulation results presented.
