An xhyphen;ray monochromator system for the AlKagr; emission line has been developed specifically for xhyphen;ray photoelectron spectroscopy. It is composed of a fine focus, high power xhyphen;ray tube with a waterhyphen;cooled rotating anode and a spherically bent quartz crystal. The parameters have been chosen to achieve very high resolution with acceptable intensity and to fulfill the geometrical conditions imposed by the electron spectrometer. A description is given of the adjustments and tests of the different components of this equipment. It is demonstrated, on the basis of spectra particularly suitable for this purpose, that a total instrumental line width of 0.3 eV or better is achieved.
