monochromatize, v.|mɒnəʊˈkrəʊmətaɪz|
[f. monochromatic a. + -ize.]
trans. To make monochromatic. So monoˈchromatized, monoˈchromatizing ppl. adjs.
1951Jrnl. de Physique XII. 268/1 It is..necessary to ‘monochromatize’ the beam. Ibid. 268/2 The monochromatized neutrons..had de Broglie wavelengths 1·06 Å and hence velocities approximately three times thermal. 1955G. E. Bacon Neutron Diffraction iv. 102 Two methods of making diffraction measurements have..been described using a neutron beam direct from the pile, without first monochromatizing. 1962Rev. Sci. Instruments XXXIII. 875/1 (heading) Preparation of bent crystals for monochromatizing x rays. 1974Nature 19 Apr. 671/2 Both structure analyses were based on diffractometer data taken with monochromatised Cu radiation. 1974Physics Bull. Oct. 443/2 The three essential components of a neutron scattering spectrometer: monochromatizing crystal, material sample and crystal for analysis of the scattered beam.
Also ˌmonochromatiˈzation, the process of making monochromatic.
1955C. B. Walker tr. Guinier & Fournet's Small-Angle Scattering X-Rays iii. 104 It might be thought that the double monochromatization and the large distance from X-ray tube to film would require a prohibitive increase in the exposure time. 1955Rev. Sci. Instruments XXVI. 564 The usual method of monochromatization consists of inserting (at the required Bragg angle) a single crystal between the x-ray source and the specimen. 1967J. Leciejewicz tr. Auleytner's X-Ray Methods in Study of Defects in Single Crystals ii. 76 The only disadvantage of the method is the very long exposure time caused by the low intensity due to precise monochromatization of the beam. |
