Influence of grating length on resolution and pulse stretching. (a) Dependence of analytically estimated resolution of the 50 l mm−1 grating with 50 nrad RMS slope error, operating in first diffraction order at 500 eV on the grating length. Solid circles – ideal VLS; open circles – VLS b2 = −1.2 × 10−6 l mm−3. (b) Pulse stretching versus open aperture upstream of the 50 l mm−1 grating operating in first diffraction order: solid line – 290 eV; dashed line – 500 eV; dotted line – 800 eV. The stars correspond to 120 mm length of grating illumination.
