• To monochromatize an X-ray beam with a stable fixed wavelength from continuous spectrum synchrotron radiation (SR), a dispersive monolithic double channel-cut monochromator (MDCM) of (771) and ($\bar{7}\bar{7}1$) was designed, and fabricated from a float-zone silicon crystal. A method of adjusting the attitude of the MDCM using a wavelength analyzer was contrived; the stability and bandwidth of the transmitted beam were evaluated by this method. It was confirmed that the central wavelength of the transmitted beam did not change at a detection limit of $5\times 10^{-9}$ within the range of half the intensity of the throughput.
