| F-ESR-ARC.01 | The ESR lattice arc magnet structure shall contain an array of regular FODO cells |
| F-ESR-ARC.02 | The 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.03 | The ESR lattice arc magnet structure shall accommodate slightly different average arc radii in the individual arcs by adjusting the drift spaces between individual elements in each FODO cell. |
| F-ESR-ARC.04 | The ESR beamline bending sections shall contain three individual dipole magnets, referred to as “super-bends”. |
| F-ESR-MAG.01 | The ESR magnets shall meet the requirements defined by the physics lattice. |
| F-ESR-MAG.02 | The ESR magnets shall have the required field quality to meet the operational needs. |
| F-ESR-MAG.03 | The “super-bends” in the ESR ARC sections shall consist of two long dipoles on either end of a short dipole. |
| F-ESR-MAG.04 | The good field region of the ESR dipoles shall extend over a horizontal range of at least 4 centimeters in the radial direction, for all operational beam energies from 5 to 18 GeV. This will take into account the orbit changes due to the reverse bends. |
| F-ESR-MAG.09 | All dipoles in the ESR, including those in IRs 6 and 8, shall be connected in series to a single main power supply. |
| F-ESR-MAG.07 | The aperture of all ESR magnets shall be large enough to accommodate the ESR vacuum chamber. |
| F-ESR-PS.01 | The ESR magnets shall be fed by a system of power supplies matched in voltage and maximum current to the specifications and requirements of the respective magnets |
