PYROLITE GRAPHITE MONOCHROMATOR AND METHOD FOR IMPROVING THE NETWORK SPREAD SPREAD OF A PYROLITE GRAPHITE MONOCHROMATOR

摘要

P According to the present invention, at least two different classes of GPFO materials having different d pitches are combined to form a composite GPFO monochromator with an increase in pitch spread (DELTA / dd) defined by the combination of the two materials GPFO, each GPFO material being oriented relative to each other so that the planes of their layers are parallel. The increase in DELTA / d d is expected to produce higher neutron beam intensities in certain types of backscatter instruments. /P
