Transmission line structures of a copper coherent forward scattering resonance monochromator (CFSRM) with d.c. glow discharge atomization have been measured by high resolution laser spectroscopy. Based on these measurements, optimal conditions have been chosen and were used for a Cu CFSRM using atomization in a pulsed glow discharge. Spectra emitted by a Grimm-type source with a Cu-Fe cathode were filtered through the Cu CFSRM. In consequence, suppression of spectral interferences from an extremely close-lying Fe emission line could be better achieved than by using a conventional grating monochromator.
