Web9 mrt. 2024 · A limitation of cryoET is its restriction to relatively thin samples. Sample thinning by cryo-focused ion beam (cryoFIB) milling has significantly expanded the range of samples that can be analyzed by cryoET. Unfortunately, cryoFIB milling is low-throughput, time-consuming and manual. Web20 jul. 2004 · yield, as the ion beam passes over the height steps, can cause thickness striations across the lamella (the ‘‘curtain effect’’) (Szot et al., 1992; Ishitani and Yaguchi, 1996). 4. The ﬁnal thinning of a lamella is performed by scan-ning the ion beam in lines and moving it inwards in ﬁxed steps (normally half a beam diameter). This
