Description	Recently, the neutron interferometer set-p installed at NPI Řež has been reconstructed in order to improve the quality of the experimental results and to enlarge its flexibility for solving a wider range of physical problems. A new sample holder permits to position, to rotate in a horizontal plane and tilt the sample in both beams inside the interferometer. The upgraded interferometer facility was tested by measuring the very sensitive coherent scattering length of Si performed by a nondispersive phase difference method. The result of this experiment is in very good agreement with the results obtained from the measurements carriedout in HMI Berlin and NIST Gaithersburg. It shows that the coherent scattering lenght can be measured using our instrument with a relative uncertainty of 0.002%.
