| F-HSR-INJ.1 | No modifications shall be required for present RHIC injector chain [5.8]. |
| F-HSR-INJ.3 | For transporting hadron beam from AGS for injection to the HSR the Y-line part of the present ATR beamline shall be modified and extended with several dipole and quad magnets (as described in the CDR Table 3.56 and Figure 3.142) in order to connect it with inner 6-4 (present Blue Ring) superconducting arc [3]. The connection shall be done at 5 o’clock Q10 (05BQ10) quadrupole. |
| F-HSR-INJ.5 | No modifications shall be required for the inner 6-4 arc in the area between 5 o’clock Q10 (05BQ10) and 4 o’clock Q6 (04BD6) magnet which transports the hadron beam to IR4. |
| F-HSR-INJ.6 | A transport line ending with a septum magnet shall be added to realize hadron beam transfer from 4 o’clock D6 (04BD6) of the 6-4 inner arc into the HSR beam pipe. |
| F-HSR-INJ.7 | A septum magnet shall be placed in the Q3-Q4 warm straight of the HSR on 4 o’clock side of the IR4. |
| F-HSR-INJ.8 | The part of the 6-4 inner (Blue) arc between D6 magnet (04BD6) and the 04B triplet shall be removed. |
| F-HSR-INJ.10 | The new HSR injection kicker system shall be installed in the center of IR4 area between triplets.  |
| F-HSR-INJ.11 | The new HSR injection kicker system shall be capable of producing the 1 mrad horizontal kick. |
| 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.1 | The magnets shall meet the requirements defined by the physics lattice.   |
| F-HSR-MAG.2 | The magnets shall have the required field quality to meet the operational needs. |
| 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.4 | The maximum acceptable magnetic stray field at the beam pipe shall be TBD gauss. |
| F-HSR-MAG.5 | The HSR sextupole families shall be wired to allow for the compensation of nonlinear chromaticity. |
| F-HSR-SNAK.12 | One additional snake shall be placed between Q7 and Q8 at 11 o’clock area of high energy arc. |
| F-HSR-SNAK.13 | One additional snake shall be placed between Q8 and Q7 in sector 1 of the 2 o’clock area. |
| F-HSR-SNAK.14 | One additional snake shall be placed sector 5 with its axis parallel to the snake in sector 11. |
| F-HSR-SNAK.16 | All the snake magnets shall operate at 4.6 K temperature. |
| F-HSR-SNAK.18 | All individual snake magnets shall be powered by individual power supplies. |
| 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). |
