Intensity distribution in the (y, t) domain at different positions. (a) Before the VLS grating, σy and σt are 948.2 µm and 14.87 fs. (b) After propagating 7.5 m after the planar VLS grating, σy and σt are 643 µm and 45.95 fs. (c) After propagating 15 m after the planar VLS grating, at the focus (exit slit), σy and σt are 8.6 µm and 45.95 fs. (d) After propagating 22.5 m after the VLS grating, σy and σt are 643 µm and 64.3 fs. (e) At the focus, the projection intensity profiles in the y dimension estimated by Shadow, SRW, analytic method, K-matrix and 6D phase space ray-tracing (this work). (f) At the focus, the projection intensity profiles in the x dimension are estimated by Shadow, SRW, analytic method, K-matrix and 6D phase space ray-tracing (this work).
