Neutron Interferometry at the National Institute of Standards and Technology

Schematic of the Neutron Interferometry and Optics Facility for Neutron Research at the National Institute of Standards and Technology. The isolated 40,000 kg room is supported by six air-springs. The system uses active vibration control to eliminate vibrations above 0.5 Hz. The temperature of the interferometer enclosure is stabilized to 5 mK precision to improve long-term phase stability (diagram also appeared in [16]).
