Description

Exclusive and diffractive final states will provide a wealth of physics at the future Electron-Ion Collider (EIC). However, measurement of these final states provide a unique challenge for detector design since many of the final-state particles wind up at very large pseudorapidities (η > 4.5), which is far beyond the acceptance of the central detector. These so-called “far-forward” particles require detectors to be integrated with the out-going hadron beamline, and therefore require special integration consideration with the accelerator complex. Here, we propose a suite of several detector subsystems which include: 1) a silicon tracking system embedded in the first, large-bore dipole magnet after the central detector, 2) two sets of “potless” Roman pot detectors for tagging protons and other charged particles over a wide range of longitudinal momenta, and 3) a zero-degree calorimeter with a W/SciFi electromagnetic calorimetry system, and a Pb/Sc sampling hadronic calorimeter for reconstructing single neutrons from nuclear breakup, and photons from π0 decay. Each detector subsystem will be discussed in detail, including considerations for technology and the related impacts with some examples from physics impact studies.
