| F-ESR-ARC.1 | The EIC ESR lattice arc magnet structure shall contain an array of regular FODO cells |
| F-ESR-ARC.2 | The EIC ESR lattice arc magnet structure shall consists of a quadrupole, a sextupole, a bending section, and a dipole corrector in each arc half-cell. |
| F-ESR-ARC.8 | The sextupole wiring scheme shall accomadate the required sextupole families needed per arc to create the 60 degree FODO cell phase advance at < 10 GeV. |
| F-ESR-ARC.10 | The sextupole wiring scheme shall accomadate the required sextupole families needed per arc to create the 90 degree FODO cell phase advance at 18 GeV. |
| F-ESR-CONT.1 | The ESR control system shall facilitate all ESR global control requirements.  |
| F-ESR-MAG.1 | The magnets shall meet the requirements defined by the physics lattice. |
| F-ESR-MAG.2 | The magnets shall have the required field quality to meet the operational needs. |
| F-ESR-MAG.3 | The sextupoles shall be sorted into appropriate “families†and powered accordingly. |
| F-ESR-MAG.10 | The two types of dipole magnets in the regular arc cells, the long dipole and the short one, shall be organized into two logical power circuits capable of being optimized subject to the physical power scheme used. |
| F-ESR-MAG.12 | The quadrupoles in the straight sections IR10, IR12, IR2, and IR4 and in the transition from the arc to the straight section structure shall be wired to provide the optimized betatron phase advance across each straight section, as required for dynamic aperture optimization. |
| F-ESR.1 | The ESR lattice shall provide a minimum dynamic aperture of 10 sigma w.r.t Gaussian electron beam distribution in all three dimensions, horizontal, vertical, and longitudinal. With the vertical emittance being half the horizontal design emittance. |
| F-ESR.2 | The minimum dynamic aperture shall be achieved in two optics configurations (60 and 90 degrees betatron phase advance per FODO cell) at all operational beam energies as per [5.9], and with one and with two low-beta insertions. |
| F-ESR.3 | The ESR shall support two low-beta insertions (colliding beam interaction regions) at IRs 6 and 8. |
| F-ESR.4 | The ESR alignment requirements are established by dynamic aperture and polarization tracking. The ESR RMS alignment tolerances shall be such that all the beam parameter listed in [5.9] can be satisfied. |
| F-ESR.5 | The ESR shall reach an availability consistent with the overall availability of the entire EIC as specified in [5.9]. |
| F-IR.8 | The IR shall be designed to ensure the hadron and electron beam collisions at the IP meet all the performance requirements set forth in [5.8]. |
| F-IR.9 | The IR shall be designed so that the electron and hadron beams have the same cross-sectional area and maximum overlap to achieve the high luminosities required in [5.8]. |
| F-IR.11 | The IR operational uptime shall match the operational uptime requirements of the EIC. |
