Treatments of a single crystal for neutron monochromator with hot press method, (1)

Since the luminosity of the pulsed neutron source with the electron linear accelerator is not so large, the increment of the reflectivity of a single crystal which is used for Bragg-reflection-type neutron spectrometer in time-of-flight experiments is necessary. This increment is achieved by treatments of a single crystal with hot press method. The conditions under which optimum reflectivity can be obtained was investigated in a germanium single crystal.
