Description
eRHIC is a proposed high luminosity, polarized Electron-Ion Collider (EIC), which would make use of the existing RHIC infrastructure. The eRHIC design is based on using one of the two RHIC hadron rings and a multi-pass Energy Recovery Linac (ERL). A polarized electron beam with an energy up to 30 GeV would collide with a number of ion species accelerated in the existing RHIC accelerator complex, from polarized protons with a top energy of 250 GeV to fully-stripped uranium ions with energies up to 100 GeV/u covering a center-of-mass energy range from 45 to 175 GeV for polarized e+p, and from 32 to 110 GeV for e+A (for large A) collisions.
eRHIC will be able to provide electron-hadron collisions in up to three interaction regions. In one of these regions will be the upgraded PHENIX detector, ePHENIX that evolves from the sPHENIX detector currently being designed. It is envisioned to fully use the sPHENIX detector at midrapidities (|eta|<1), followed by a sPHENIX-Forward upgrade with additional modifications specific to ePHENIX.
This presentation will describe the ePHENIX approach and goals and requirements for day-1 physics at eRHIC.
