Title: Demonstration of Achromatic Cold-Neutron Microscope Utilizing Axisymmetric Focusing Mirrors.
Published: April 21, 2013
Abstract: An achromatic cold-neutron microscope with magnification 4 is demonstrated. The image-forming optics is made of nested coaxial mirrors of full figures of revolution, so-called Wolter optics. The spatial resolution, field of view, and depth of focus are measured and compared with ray-tracing simulations. Methods of increasing the resolution and magnification are discussed, as well as the scientific case for the neutron microscope. In contrast to traditional pinhole-camera neutron imaging, the resolution of the microscope is determined by the mirrors rather than by the collimation of the beam, leading to possible dramatic improvements in the signal rate and resolution.
