This article describes the design and expected performance of the ATHENA detector in the Electron-Ion Collider. The careful technology choices enable fine tracking and momentum resolution, high-performance calorimetry, wide range hadron identification, and near-complete hermeticity. The article also evaluates the detector technology choices, technical challenges, and R&D required to meet those challenges.
ATHENA has been designed as a general purpose detector capable of delivering the full scientific scope of the Electron-Ion Collider. Careful technology choices provide fine tracking and momentum resolution, high performance electromagnetic and hadronic calorimetry, hadron identification over a wide kinematic range, and near-complete hermeticity. This article describes the detector design and its expected performance in the most relevant physics channels. It includes an evaluation of detector technology choices, the technical challenges to realizing the detector and the R&D required to meet those challenges.
