We demonstrate a two phase grating multi beam neutron interferometer by adopting a modified Ronchi setup [1] to a neutron beam in a far-field regime. The functionality of the interferometer is based on the universal moiré effect that was recently implemented for X-ray phasecontrast imaging in the far field regime. Interference fringes were achieved with monochromatic, bichromatic, and alychromatic neutron beams; for both continuous and pulsed beams. This far-field neutron interferometry allows for the utilization of the full neutron flux for the precise measurements of potential gradients, and expands neutron phase-contrast imaging techniques to more intense polycromatic neutron beams.
