Figure 14
Diffraction efficiency of a blazed diffraction grating of 600 lines mm−1 in zero and first order at 100 eV, operated on-blaze. The Io-beam profile (shifted and normalized to the zero-order peak) is also shown for comparison (black points). Second-order radiation in the incident beam (photon energy 200 eV) which is not suppressed creates a first-order diffraction peak at 2θ = 10.5°. |
