Construction and testing of the instrument for neutron holographic study at the Budapest Research Reactor

摘要

Neutron scattering device dedicated to neutron holography experiments is described. The device is operating at a constant wavelength prepared by a double focusing monochromator. It is equipped by highly efficient shielding, proper collimator, Eulerian cradle, monitor detector, gamma-ray, and neutron detectors as well. Relevant software serves as control for the measurement and data collection. The harmonized application of the components enumerated above makes our device extremely efficient and unparalleled. Two atomic resolution neutron holographic experiments carried out illustrate the efficiency and power of the instrument. © 2010 American Institute of Physics Article Outline INTRODUCTION INSTRUMENTAL REQUIREMENTS OF A NEUTRON HOLOGRAPHIC MEASUREMENT DESCRIPTION OF THE INSTRUMENT TEST MEASUREMENTS Holographic study of SnCd0.0026 alloy Measurement on NH4Cl sample CONCLUSIONS
