| Parents | |
| F-EIS- RCS-LATTICE-ARC.1 | The EIC RCS lattice arc magnet structure shall contain an array of 160 regular FODO cells to bend the beam and to control the beam optics broken into two arcs. The arc FODO cells shall consist of a horizontally focusing\defocusing quadrupole magnet followed by a correction dipole; then, followed a dipole bending magnet, and then followed by a sextupole correction magnet. With a drift space between these elements of > 0.1m long |
| F-EIS- RCS-LATTICE-STRAIGHT.1 | The RCS will have two straight sections connecting the two arcs. Each straight shall be comprised of 2 FODO cells on each end for matching into the arcs and with one of the drifts long enough to accommodate extraction or injection and the necessary septa magnets. The straights shall also have 4 FODO cells in the center with enough space to accommodate 8 SRF cryo-modules to generate 130 MV of accelerating voltage. |
| F-EIS- RCS-MAG.5 | The good field region of the dipoles shall extend over a horizontal range of at least 15 mm in the radial direction, for all operational beam energies from 0.75 to 18Gev. |
| F-EIS- RCS-MAG.12 | The aperture of all magnets shall be large enough to accommodate the vacuum chamber. |
| F-EIS-RCS-MAG.1 | The magnets shall meet the requirements defined by the physics lattice. |
| F-EIS-RCS-MAG.5 | The EIC RCS lattice arc FODO cells shall consist of a horizontally focusing\defocusing quadrupole magnet followed by a correction dipole, then a followed by a sextupole correction magnet and a dipole bending magnet. With a drift space between these elements of > 0.3m long. |
| F-EIS-RCS-MAG.6 | There shall be sections at the ends of the ARCS and the straight sections to match the optics. |
| F-EIS-RCS-MAG.10 | The straight sections IR2,4,10 and 12 shall use FODO cells for optic control. |
| F-EIS-RCS-MAG.13 | There shall be only one family of dipoles in the RCS. |
| F-EIS-RCS.9 | The RCS lattice shall provide a maximum dynamic aperture of 3 sigma w.r.t Gaussian electron beam distribution in transverse dimensions. |
| F-EIS-RCS.10 | The RCS off-momentum aperture shall reach 1.0% dp/p. |
| F-EIS-RCS.11 | Quadrupoles and sextupoles shall be aligned to with 0.2 mm RMS or better with a 2.5 sigma cutoff. |
| F-EIS-RCS.12 | The alignment of the dipole field with respect to the vertical axis shall be less +/- 1 mrad rms with 2 sigma cut-off. |
| 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 |
| F-IR.11 | The EIC IR electron and hadron spin manipulation components shall be designed to provide the spin orientation at the IP as specified in the MPT [EIC Document: EIC-SEG-RSI-005]. |
