| Parents | |
| G-EIS.2 | The EIS shall provide an electron beam having sufficient energy to meet the ESR beam requirements as set forth in [5.9]. |
| G-EIS.3 | The EIS shall provide an electron beam with the RMS bunch momentum spreads at extraction which meet the ESR beam requirements as set forth in [5.9]. |
| G-EIS.4 | The EIS pre-injector shall provide an electron beam to the ESR having a horizontal beam emittance which is compatible with operation of the ESR. |
| G-EIS.5 | The EIS pre-injector shall provide an electron beam to the ESR having a vertical beam emittance which is compatible with operation of the ESR. |
| G-EIS.6 | The EIS shall inject into the ESR at a rate of 1[Hz]. |
| G-EIS.7 | The EIS shall inject one bunch into the ESR whilst being able to provide 2 bunches per injection cycle. |
| G-EIS.9 | The EIS shall provide an electron beam to the ESR having the bunch charge at extraction to meet the beam requirements as set forth in [5.9]. |
| G-EIS.8 | The EIS shall provide an electron beam to the ESR having RMS Bunch lengths at extraction to meet beam requirements as set forth in [5.9]. |
| G-EIS.10 | The ESR bunch replacement pattern will be defined by 1.the required polarization pattern to be provided to the experiments, 2.decay rates and 3. The RF cogging limitations of the beam transfer between RCS and ESR. |
