Figure 1
(a) The sample-mounting grid is affixed in a standard magnetic base with epoxy. This allows them to be manipulated by automated mounting systems. For comparison, a Hampton Research-style copper magnetic sample pin is also shown. (b) A jig is used to hold grids in place as the epoxy cures. The jig consists of two parts: the base piece from a standard uni-puck and a specialized cover machined from aluminium. Guide holes in the cover hold grids vertically as the epoxy sets. (c) Cutaway view of a uni-puck enclosure (tan) with two grids (white) inside. (d) Schematic of the sample-mounting grid with the fiducial ports highlighted in red. Units are shown in millimetres.
