A novel method for the in situ visualization and profilometry of a plasma-facing surface is
demonstrated using a long-distance microscope. The technique provides valuable in situ
monitoring of the microscopic temporal and morphological evolution of a material surface
subject to plasma–surface interactions, such as ion-induced sputter erosion. Focus variation
of image stacks enables height surface profilometry, which allows a depth of field beyond
the limits associated with high magnification. As a demonstration of this capability, the …
