| Description: | The ESR vacuum chamber shall provide sufficient horizontal and vertical aperture to accommodate; a +/-15 sigma beam, where the vertical RMS beam size is based on the emittance of a fully coupled beam, plus an additional 10 mm horizontal and 5 mm vertical margin to account for expected orbit errors. | ||

| 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 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.02 | The typical (standard) vacuum chamber aperture shall be 80 x 36 mm. |
| P-ESR-VAC.03 | Special aperture requirements and/or aperture file shall be provided by or approved by physics. |
