This is a CFNS Ad-Hoc Meeting. See the CFNS conferences page for other events.
This workshop aims to evaluate the physics potential and technical feasibility of implementing a fixed-target program at the future Electron-Ion Collider (EIC). Inspired by successful initiatives such as SMOG2 at LHCb and the STAR fixed-target program at RHIC, we propose to explore how such a setup could complement the collider mode and significantly broaden the EIC’s scientific reach.
A fixed-target configuration would provide unique access to poorly explored regions of QCD: high Bjorken-x, low Q^2, exclusive and diffractive processes, cold nuclear matter effects, and hadronization at large x. It would also enable studies with polarized and nuclear targets, and open the door to heavy-ion collisions (A+A') at EIC energies, complementing the RHIC Beam Energy Scan.
In addition to its impact on nuclear and particle physics, such a program could deliver valuable data for space radiation research, particularly through precise cross-section measurements relevant to cosmic-ray interactions—building on experience from target-wire experiments at RHIC.
The workshop will bring together experts in accelerator design, detector integration, and QCD theory to assess the physics case, target technologies (storage cells, wire targets), and integration challenges at IP8. The goal is to evaluate the viability and benefits of adding a fixed-target mode to the EIC’s capabilities.
