| 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.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-STRAIGHT.3 | There shall be matching sections at the ends of each of the straight sections to compensate for the different FODO cell lengths wrt the arc FODO cells imposed by geometric constraints. |
| 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-ESR-LATTICE.2 | The IR electron lattice design shall adjust the phase advance between the IP and the arc on each side to support the correction of chromatic effects. |
| F-IR-ESR-LATTICE.3 | The IR electron lattice elements shall provide apertures in the near-IR quadrupoles large enough to transmit the synchrotron radiation created by magnets on the other side of the IP. |
| F-IR-ESR-LATTICE.7 | The IR electron lattice shall provide space for detectors to tag scattered electrons on the downstream side of the IP (Rear Side). |
| F-IR-ESR-LATTICE.14 | The IR electron lattice design shall create a multiple of 180deg horizontal phase advance between the two crab cavities. |
| F-IR-ESR-LATTICE.11 | The IR electron lattice shall accommodate the crossing angle required by the electron beam at the IP. |
| F-IR-ESR-LATTICE.15 | It shall be possible to remove any horizontal/transverse coupling introduced due to the detector solenoid and ESR ring tilt in the IR electron lattice. |
| F-IR.2 | The IR shall guide the hadron and electron beams to collide at the IP of IR6. |
| F-IR.4 | The IR electron and hadron beam lines shall have the linear lattice functions matched to the incoming and outgoing arcs of the ESR and HSR respectively. |
| 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. |
