Figure 8
Deduction of the vertical FEL focal size from measured PMMA imprint sizes (vertical radius). The linear fit of the semilog plot of measured radius2 as a function of FEL pulse intensity Ln(I) leads to a slope which is proportional to the focus size. Here the longitudinal position includes an offset of +10 mm relative to the nominal one. The slope in this figure corresponds to a vertical focal size of (11.1 ± 0.8) µm FWHM.
