Development of Monochromator and Filter of Graphite for Neutron and X-ray

Abstract

I introduce graphite used as neutron monochromator and filter. There are gas phase method and solid phase method for making graphite. Panasonic Corporation has been working on solid phase method. Here, the comparison between the vapor phase method and the solid phase method, and the subsequent development will also be explained. Graphite block made by the solid phase method is used in JRR-3 etc.
