Focusing Neutrons to Study Small Samples
We built a compact (25 cm long) focusing device for neutron diffraction studies of very small samples (mm3 or less). Neutrons are reflected on Ni-Ti supermirror surfaces both in the horizontal and in the vertical plane. The focusing angle in the horizontal plane is variable to choose an optimal ratio between intensity and angular resolution. A gain in intensity of four times was obtained. The new stage of the focusing system should provide a gain up to 7 times.
