Ion thinning
WebPubMed WebThis is partly due to the fact that metallurgists and crystal physicists having solved most of the structural and crystallographic problems in metals have begun to show a widening interest in the much more complicated structures of minerals, and partly to recent progress in experimental techniques, mainly the availability of ion-thinning devices.

WebThe Ion-sculptor FIB column introduces a new way of FIB-processing: by minimizing sample damage you’ll maximize sample quality and perform experiments faster at the same time. Manipulate your samples precisely and fast by using up to 100 nA current without compromising FIB resolution. WebThus, the application of ion thin- ning to martensitic samples also appears to be useful since it permits the details of the bulk phase to be re- tained for study in thin foils. Finally, it is appropriate to present one possible ex- planation for the suppression of spontaneous relaxation in ion-thinned foils.
