Test of a four plate neutron interferometer

  • Published:
Zeitschrift für Physik B Condensed Matter

Abstract

A monolithically designed four plate perfect crystal interferometer was tested. The experimental results were compared to calculated interference patterns based on plane wave theory. Inside the four plate system are three independent interferometer loops which permit the definition of three effective phase shifts and determine the intensity modulation behind the interferometer crystal. Absorbing phase shifters cause a partial beam path detection and, therefore, influence the interference pattern by their individual location. Several features of multiplate interferometry and a modified phase echo system are discussed.
