| Parents | |
| F-EIS-GUN.1 | The pre-injector shall have a high voltage (HV) DC electron gun as the electron source for the EIC. |
| F-EIS-GUN.2 | The pre-injector electron gun shall produce all the bunch patterns required to deliver the ESR beam requirements set forth in [5.9]. |
| F-EIS-GUN.3 | When illuminated with a laser of the correct wavelength (780nm+/-5nm) the pre-injector electron gun shall produce the polarized electrons required to operate the EIC. |
| F-EIS-GUN.4 | The planned building utility requirements (Power, Temperature, Humidity, etc.) shall be consistent with the requirements necessary for the gun to meet its beam performance requirements |
| F-EIS-GUN.5 | A compact Mott Polarimeter shall be used to inspect the polarization level and Quantum efficiency of the super lattice GaAs cathode, this system is not part of the gun chamber. |
| F-EIS-GUN.6 | The pre-injector shall have a low energy transfer line from the gun into the beam compression "Bunching" section |
| F-EIS-GUN.7 | The low energy transfer line shall have an additional branch between the Gun and the Bunching section which can transfer individual electron bunches into the diagnostic beamline section. |
| F-EIS-GUN.8 | The low energy transfer line shall have a laser port between the Gun and the Bunching section which will allow an optical path for the laser to illuminate the cathode face of the gun. |
| F-EIS-GUN.9 | Following the gun, there shall be multiple groups of magnets required to control the electron beam. |
| F-EIS-GUN.10 | The gun shall have steering coils to direct the liberated electrons (These can be reused from the existing Gun system.) |
| F-EIS-GUN.11 | To characterize and control the fresh bunches the low energy transfer line from the Gun to the Buncher shall contain a plunging transverse profile monitor, a bunch charge monitor, beam loss monitors, and beam position monitors |
| F-EIS.18 | The EIS Pre-Injector shall be able to create a spin polarized electron bunch and accelerate it to 400MeV ready for transport to the 400 MeV-transfer line to the RCS. |
| F-EIS.17 | The EIS Pre-Injector shall consist of 3 sub-systems: 1. An electron gun section, followed by 2. A low energy transfer line and bunching section, followed by 3. A LINAC section |
| F-EIS.19 | The EIS Pre-Injector shall create bunches which meet the requirements set forth in [5.9]. |
