Upgrade of the Cold Neutron Imaging Instrument, Phase Grating Roll Alignment System

The National Institute of Standards and Technology (NIST) is seeking a quotation for the upgrade of the Cold Neutron Imaging Instrument, Phase Grating Roll Alignment System. The system requires high precision rotation stages with a clear aperture to allow the beam to pass unattenuated, as well as cabling, control hardware, and control software. The quotation should include a firm-fixed-price for each line item, including shipping costs and tariffs. The offeror must demonstrate that their proposed system meets or exceeds each minimum requirement described in the statement of work document. Key features of the required system include: • High precision rotation stages with a resolution better than 0.00005 degrees • Clear aperture to allow the beam to pass unattenuated • Cabling, control hardware, and control software • Ability to translate the gratings in the vertical direction • Mass of the alignment system should be kept to as low as achievable • The system should be able to rotate a full 360° with high resolution
