| G-ESR.02 | The ESR shall have a depolarization time long enough to ensure an average polarization of 70%, assuming an injected polarization level of 80% and a bunch replacement rate of up to two bunches per second. |
| G-ESR.03 | The ESR shall provide electron bunches having the bunch parameters specified in the MPT. [Document#:EIC-SEG-RSI-005] |
| Children | |
| P-ESR-VAC.07 | There shall be no upper pressure limit as long as the average pressure is maintained. |
| P-ESR-VAC.06 | The average vacuum level in the ESR Arc sections after conditioning (for 1000Ahrs) shall be <5x10-9 Torr. |
| P-ESR-VAC.08 | On 15 m on each side (or one vacuum sector) of the SRF cavities shall be processed to class ISO 5. |
