Experimental Equipment of the EIC

The Electron-Ion Collider (EIC) is a new, innovative, large-scale particle accelerator facility planned for construction at Brookhaven National Laboratory. The EIC will study protons, neutrons and atomic nuclei with the most powerful electron microscope, in terms of versatility, resolving power and intensity, ever built. The EIC will address some of the most fundamental questions in science regarding the visible world, including the origin of the nucleon mass, the nucleon spin, and the emergent properties of a dense system of gluons. EIC detectors are essential to access the physical observables described by theoretical calculations. In contrast to symmetric ee and pp colliders, the asymmetric nature of collisions at the EIC leads to unique detector requirements. The hadron endcap, barrel, and electron endcap detector systems see very different particle distributions, in terms of both momentum and particle types. Likewise, the performance requirements on these detector systems vary significantly between the detector regions. This is reflected by the critical detector requirements for the track, vertex, and energy resolution and particle identification separation summarized in the EIC Users Group Yellow Report (YR). The YR has become the cornerstone on which detector proposals are being developed. In this talk I will present the detector requirements and design driven by the EIC physics program and defined by the EIC Community, and an overview of the ongoing detector proposal development efforts.
