Overview of the EIC detector concepts and R&D

The EIC detector is required to have excellent performance for a broad range of exciting EIC physics measurements, providing powerful investigations not currently available that will dramatically advance our understanding of how quantum chromodynamics binds the proton and forms nuclear matter. The expected physics and the accelerator's parameters drive the design in a significant way while many other aspects, constraints and boundary conditions have to be taken into account. The design of the detector is based on the collider detector which is optimized for deep inelastic (DIS), semi-DIS, other exclusive reactions as testing grounds. A general purpose and a high hermeticity are thus a crucial requirement as the EIC detector. Such a detector is typically composed of vertex, tracking, particle identification, EM and hadron calorimeter detectors. These detectors are arranged for e-going, central and hadron going directions to meet the demand of each direction. The EIC detector designs have been developed by different collaborators in different laboratories such as BEAST, ePHENIX/eSTAR, JLEIC, and SiEIC. A basic common features of the general EIC detector concept are to be discussed as well as introducing uniqueness of these different detector and possible detector technology choices.
