| F-HSR-VAC-BS.6 | Beam screens shall not be required for the warm beam pipe sections of the HSR but other means to inhibit SEY, likely NEG, are required. |
| F-HSR-VAC-BS.7 | Beam screens shall be designed to fit into the HSR round cold beam pipes in all seven HSR arcs. |
| F-HSR-VAC-BS.9 | Beam screens shall be designed to fit through the cold mass interconnect. |
| F-HSR-VAC-BS.8 | Beam screens shall be designed to fit into the cold beam pipe of the HSR arc magnets. |
| F-HSR-VAC-BS.10 | The impedance of the screen design, including the screen with RF finger bellows at the cold mass interconnects shall not exceed the the global impedance budget which has been defined by approved by beam physics . |
| F-HSR-VAC-BS.11 | The beam screens shall be designed to be mechanically resistant to eddy-current forces resulting from a magnet quench. |
| F-HSR-VAC-BS.12 | The beam screen design for the transition-crossing jump quadrupole beam pipes shall enable a magnetic field transition time of 40 ms or faster. |
| F-HSR.8 | The HSR shall provide a dynamic aperture of > 6σ under colliding beam conditions. |
| F-HSR.9 | The physical aperture for the circulating hadron beam shall be > 10σ horizontal and vertical. |
