Abstract

An interferometer for very cold neutrons using three phase gratings sputter-etched into quartz-glass plates has been developed for fundamental physics experiments. The lines of the phase gratings were aligned parallel to 1 μrad by light interferometry. A prototype interferometer with an overall length of 50 cm has been tested for λ = 102 Å (v = 38.7 m/s) neutrons.
