Abstract
Composite germanium monochromators are in the beginning of their appli cation in neutron diffraction. In order to optimize their properties f or high-resolution neutron powder diffraction we significantly improve d the alignment procedure of the individual wafers used for building t he monochromator plates, as we added the tin necessary for soldering w ith a sputtering technique instead of tin foil spacers. Sputtering cou ld also be replaced by evaporation giving similar results.
