| 内容記述 | The design and preliminary performance data are presented for a monochromator based on two multilayer X-ray mirrors. The monochromator is based on mirrors with a d-spacing of 40 A and is designed to operate in the 5-75 A wavelength regime which can be varied by interchanging the mirrors with ones of different d-spacing. The multilayer mirrors are fabricated using sputter deposition and typically consist of 40 layer pairs of W and C. Except for W/Si, which shows 1-2 percent better reflectivities over the 7-40 A range but 4-10 percent poorer reflectivities for wavelengths longer than 40 A and shorter than 7 A, calculations performed using other combinations of materials generally show poorer reflectivities over the wavelength range of interest. Plans for a four-mirror version of the monochromator that will have increased resolution are also presented. |
