| F-EIS-RCS-MAG-SEXT.1 | The maximum integrated field strength of the FODO sextupoles needs to be sufficient to provide chromatic correction at 18 GeV. |
| F-EIS-RCS-MAG-SEXT.2 | Sextupoles shall be sorted into “families”, with the family structure dependent on the linear lattice configuration (betatron phase advance per FODO cell). |
| F-EIS-RCS-MAG-SEXT.3 | Sextupoles shall be powered based on their “families”, with the family structure dependent on the linear lattice configuration for arcs and straight sections. |
| F-EIS-RCS-MAG.1 | The magnets shall meet the requirements defined by the physics lattice. |
| F-EIS-RCS-MAG.2 | Magnets should be aligned to with 0.2 mm RMS or better with a 2.5 sigma cutoff |
| F-EIS-RCS-MAG.3 | The aperture of all magnets shall be large enough to accommodate the beamline vacuum chamber. |
| F-EIS-RCS-MAG.10 | The straight sections IR2,4,10 and 12 shall use FODO cells for optic control. |
| F-EIS-RCS.9 | The RCS lattice shall provide a maximum dynamic aperture of 5 sigma w.r.t Gaussian electron beam distribution in transverse dimensions. |
| F-EIS-RCS.10 | The RCS off-momentum aperture should reach 1.5% dp/p. |
| F-EIS.1 | The EIS polarized electron source shall create a spin polarized beam of electrons and inject them into the ESR. |
| F-EIS.2 | The injected spin polarized electron beam shall meet all the parameters set forth in the MPT. [Document#:EIC-SEG-RSI-005] |
| F-EIS.3 | The EIS shall consist of five sections: 1. Pre-Injector 2. LTR Transfer Line 3. BAR 4. RCS 5. RTE Transfer Line |
