ScholarBank@NUS Repository. https://doi.org/10.1016/j.nimb.2009.03.076 | Abstract: | The central peak widths of the 2D-autocorrelation function have been investigated as a Figure of Merit (FoM) of focus quality in nuclear microscopy using a quadrupole triplet lens system. The beam focus could be reliably characterised for direct scanning transmission ion microscopy (direct-STIM) images obtained with fluences as small as 5.8 × 109 ions cm- 2 which colocalisation tests showed did not introduce significant beam-induced changes in the cells. © 2009 Elsevier B.V.
