This report describes the physics case, the resulting detector requirements, and the evolving detector concepts for the experimental program at the Electron-Ion Collider (EIC). The EIC will be a powerful new high-luminosity facility in the United States with the capability to collide high-energy electron beams with high-energy proton and ion beams, providing access to those regions in the nucleon and nuclei where their structure is dominated by gluons. Moreover, polarized beams in the EIC will give unprecedented access to the spatial and spin structure of the proton, neutron, and light ions. The studies leading to this document were commissioned and organized by the EIC User Group with the objective of advancing the state and detail of the physics program and developing detector concepts that meet the emerging requirements in preparation for the realization of the EIC. The effort aims to provide the basis for further development of concepts for experimental equipment best suited for the science needs, including the importance of two complementary detectors and interaction regions. This report consists of three volumes. Volume I is an executive summary of our findings and developed concepts. In Volume II we describe studies of a wide range of physics measurements and the emerging requirements on detector acceptance and performance. Volume III discusses general-purpose detector concepts and the underlying technologies to meet the physics requirements. These considerations will form the basis for a world-class experimental program that aims to increase our understanding of the fundamental structure of all visible matter.

The generic R&D program was and is a vital part of the overall EIC efforts with over 280 participants from 75 institutions. Despite moderate funding, many groups are making excellent progress on many vital technologies needed for an EIC detector. The generic R&D program was not the only source of support for R&D relevant for an EIC detector. Several National Laboratories, among them BNL, JLab, ANL, and LANL, supported EIC detector R&D through Laboratory Directed Research & Development Programs (LDRDs) and many university groups in and outside of the US, active in the many R&D projects received support from their respective department and/or funding agencies. The EIC also benefited substantially from R&D conducted for many HEP and NP experiments such as ALICE and LHCb at CERN, Panda at GSI and Belle-II at KEK.
