F-DET-ANC-B0.3	B0-system must fit and be integrated into the warm area of the B0-dipole. The B0-systems shall require appropriate power and cabling to support operation of the detector elements.Should have survey marks to determine their physical location
F-DET-ANC-B0.5	B0-system must operate at a full projected EIC luminosity and must be resistant to extreme background conditions, high neutron flux in particular, at the levels specified by the simulation studies
F-DET-ANC-LOWQ2.5	LowQ2 system must operate at a full projected EIC luminosity
F-DET-ANC-LOWQ2.6	LowQ2 system must be resistant to extreme background conditions (synchrotron radiation, bremsstrahlung events and slow neutrons in particular) at the levels specified by the simulation studies
F-DET-ANC-LUMI.1	The luminosity detectors shall be composed of a Pair Spectrometer (PS) with 2 stations (above and below zero degree line) with tracking layers in front, and a direct photon CAL along the zero degree line.
F-DET-ANC-LUMI.2	The PS must measure the energy and position of e+e- pairs from bremsstrahlung conversions. The direct photon CAL must measure the energy of the large bremsstrahlung flux while mitigating the high rates of background synchrotron radiation.
F-DET-ANC-LUMI.3	Must be resistant to extreme background conditions, magnetic interference and radiation.
F-DET-ANC-OFFMO.3	Must be resistant to extreme background conditions, high neutron flux in particular, at the levels specified by the simulation studies.
F-DET-ANC-ROMAN.2	RPOT will be integrated into the accelerator vacuum system.
F-DET-ANC-ROMAN.4	Must be resistant to extreme background conditions, high neutron flux in particular, at the levels specified by the simulation studies.
F-DET-ANC-ZDC.4	Must be resistant to extreme background conditions, high neutron flux in particular, at the levels specified by the simulation studies.
F-DET-ANC-ZDC.6	Must be compact enough to fit in the limited space allocated in the accelerator tunnel
F-DET-ANC.6	The EIC ancillary detectors will require adequate infrastructure resources (i.e. power, cooling, cryogens, etc.) to ensure it can function reliably during continous operations.
F-DET-ANC.8	The EIC ancillary detectors and its support systems must fit in the available space AND provide adequate plenums and pathways for the delivery of services, resources and communications, and for the removal of heat and waste during operations.
F-DET-ANC.7	The configuration of the EIC ancillary detectors within the detector will be coordinated to ensure efficient operation and to minimize adverse interactions between sub-systems.
F-DET-ANC.9	A structural support infrastructure must be provided that supports the weight of the EIC ancillary detectors and peripheral equipment, and safely distributes that load to the ground.
