| F-HSR-INJ.11 | The new HSR injection kicker system shall be capable of producing the 1 mrad horizontal kick. |
| F-HSR-INJ.12 | The new HSR injection kicker system shall be capable of producing kicker pulse with 7.0 ns rise time. |
| F-HSR-INJ.13 | The new HSR injection kicker system shall include 20 strip-line kickers , with a gap of 5.9 cm and voltage +/- 17 kV. |
| F-HSR-INJ.14 | The present injection kicker system at 5 o’clock area shall be removed. |
| F-HSR-MAG-PS.1 | The HSR 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 |
| F-HSR-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-MAG.5 | The HSR sextupole families shall be wired to allow for the compensation of nonlinear chromaticity. |
| F-HSR-SNAK.1 | Six Siberian Snakes shall be required.Two existing snakes, one in the RHIC sector 9 outer ring and one in the RHIC sector 3 inner ring will not move. The additional 4 snakes will be positioned as specified in the follwing requirements. |
| F-HSR-SNAK.2 | Four snakes shall be added around the HSR. |
| F-HSR-SNAK.3 | Additional snakes shall repeat the internal structure of existing Snakes. [5.8]Â |
| F-HSR-SNAK.4 | Additional snakes shall consist of four superconducting helical dipole magnets. |
| F-HSR-SNAK.5 | Each helical module shall be 2.4 m long. |
| F-HSR-SNAK.6 | The helical modules shall be separated by a 32 cm drift space.  |
| F-HSR-SNAK.7 | The maximum required field of each magnet shall be 4 T.  |
| F-HSR-SNAK.8 | All snake magnets shall have the same helicity as the helical dipole field.  |
| F-HSR-SNAK.10 | Two snakes shall be transferred over from the Blue ring. |
| F-HSR-VAC.1 | The HSR vacuum system shall be modified to accommodate worst case dynamic heat load (0.72 A beam with 290 bunches at 19.8·1010 ppb). |
| F-HSR.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 [6.9] can be satisfied. |
| F-HSR.12 | The HSR shall deliver spin polarized ion beams with time-averaged polarization of at least 70 percent. |
| F-HSR.13 | The HSR lattice shall have features to preserve the polarization from injection to top energy. |
