| Parents | |
| F-HSR-STR-MAG.1 | The magnets shall meet the requirements defined by lattice designs for all operational scenarios. |
| F-HSR-STR-MAG.2 | The magnets shall have the required field quality to meet the operational needs. |
| F-HSR-STR-MAG.3 | The HSR sections consisting of Blue Ring segments shall provide the same quench protection functionality as Yellow Ring segments (diode polarity). |
| F-HSR-STR-MAG.8 | The HSR existing magnets, beam components and instrumentation in IR2 shall be moved as required to realize the IR2 lattice design. |
| F-HSR-STR-MAG.9 | The HSR shall use existing superconducting magnets from RHIC in the new IR2 lattice, no new magnets are required for IR2. |
| F-HSR-STR.1Ê | The HSR proton beam shall be ramped from injection energy to an operation energy of up to 275 GeV. |
| F-HSR-STR.2Ê | The HSR shall be designed for changing beam optics between the relaxed state for injection to collision beam optics with beam in the machine. |
| F-HSR-STR.3 | The HSR beam at full energy shall be synchronized to the revolution frequency of the electron beam. |
| F-HSR-STR.4 | The HSR systems shall provide the capability to operate with at least +/-21 mm radial shift of beam orbit in all arcs. |
| F-HSR-STR.8 | The HSR shall provide a dynamic aperture of > 6σ under colliding beam conditions. |
| F-HSR-STR.9 | The physical aperture for the circulating hadron beam shall be > 10σ horizontal and vertical. |
| F-HSR-STR.10 | The HSR alignment requirements are established by dynamic aperture and polarization tracking. The HSR RMS alignment tolerances shall be such that all the beam parameters listed in the MPT [Document: EIC-SEG-RSI-005] can be satisfied. |
| F-HSR-STR.11 | The operational availability design target for the IR shall be consistent with the operational availability target for the overall EIC as set forth in Electron-Ion Collider Global Requirements. [Document:EIC-ORG-PLN-010] |
| F-IR-HSR-LATTICE.2 | The hadron beamline lattice elements through the IR shall have a large enough aperture throughout to accommodate a minimum of 10σ spread in x and y of the incoming hadron beam at all energies without obstruction for all energies set forth in [5.8]. |
| F-IR-HSR-LATTICE.14 | At the IP of the hadron lattice the dispersion, its derivative and alpha shall all be 0 ,and the beta βx βy shall be chosen to deliver the colliding beam parameters set forth in [5.8] |
| 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. |
