Figure 1
Panel (a) shows a photograph of the EIS-TIMEX endstation. In panel (b) the single-shot craters on the YAG:Ce are shown, obtained at different positions on the optical axis of the focusing ellipsoidal mirror. Panels (c) and (d) are the horizontal and vertical projections of the craters. The values of the projections are obtained by integrating the spots over the selected direction and merging the results in single graphs [panels (c) and (d)]. Stars indicate the smallest spot dimensions characterized by the smallest FWHM value. |
