| 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.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-LINAC-BNCHR-MAG-CORR.1 | Multiple air-core Steering coils shall be placed in the bunching to correct the bunch position if needed (Number and positions TBD) |
| F-EIS-LINAC-BNCHR-MAG-HELM.1 | The beam path between the gun and 1st bunching shall be surrounded by a large external magnetic field canceling Helmholtz coil to trim out the earths magnetic field. |
| F-EIS-RCS.14 | The RCS shall transmit polarization with a 95% efficiency. |
| 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. |
