| 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. |
| Children | |
| P-EIS-HETL-INST-BPM.1 | The BPM measurement resolution should be 100 um or less, for a bunch charge range of 100 pc to 28 nC. < 100 um |
| P-EIS-HETL-INST-BPM.2 | The BPM acquisition rate shall depend on the rate of transfer from RCS-to-ESR, expected twice per second. 2.5 uS |
| P-EIS-HETL-INST-BPM.3 | The number of BPMs in the RCS-to-ESR transport line shall be 10 ea |
| P-EIS-HETL-INST-BPM.4 | The BPMs shall be located by the dipole correctors at every 2nd Quad |
| P-EIS-HETL-INST-BPM.5 | The BPM pick-up alignment accuracy to each nearby quad shall be within 100 um |
| P-EIS-HETL-INST-BPM.6 | The BPM button style pick-ups shall be rotated TBD degree configuration to avoid the synch light near the dipole bends |
| P-EIS-HETL-INST-BPM.7 | The BPMs shall be used as input for beam trajectory correction and/or feedforward to optimize transmission efficiency |
| P-EIS-HETL-INST-BPM.8 | The BPMs shall be used to measure the transport lattice. |
| P-EIS-HETL-INST-BPM.9 | The BPMs located in the high dispersion regions, shall monitor relative changes in the beam energy. |
