WebOverview. The instrument is an FEI Helios NanoLab 600i DualBeam SEM/FIB, containing both a focused Ga+ ion beam ("Tomahawk") and a high resolution field emission scanning electron ("Elstar") column. Combined with advances in patterning, scripting, and a suite of accessories, these features make milling, imaging, analysis, and sample preparation ... Weband thinned stepwise by milling the top surface layers with decreasing beam currents until a thin slice remains at the selected spot. Typical thinned areas are 15-20 /am wide and 5-10/am deep and can be prepared in 2-2.5 h milling time. Before the FIB thinning a protective metal layer floor coverings maryborough qld
