36 Fischione model 1040 nanomill Filament-based ion source combined with electrostatic lens system Accelerating voltages range from 50 eV to 2 kV and are continuously adjustable Beam current density is up to 1 mAcm2 Beam diameter can be reduced to 1 m at 2 kV Milling angles range from -12 to 30 degrees Ar ion beam can be targeted at one spot on the specimen or scanned within a selected area LN2 conductive cooling Stage temperature can be reduced to -170 degrees Everhart-Thornley detector SED-based imaging technology with 3 mm field of view Set up to post-process FIB lamella and remove Ga ion beam damage. Gatan model 695 PIPS-2 Two penning Ar ion guns with low energy focusing electrodes Milling angles can be changed from -10 to 10 degrees for each gun independently Ion beam energies range from 100 eV to 8 kV Ion current density is 100 mAcm2 at the peak Whisperlock with X Y stage to center the region of interest for re-polish Digital Zoom microscope that oper- ate in real time during milling Color image stage in Digital Micrograph Accommodates 2.3 mm 3 mm conventional TEM disks and FIB lamella LN2 specimen cooling Set up as a post-processing step for FIB lamella to remove FIB Ga ion beam damage. Scanning probe microscopy results taken from the three regions in the surrogate TRISO particles which illustrate the nanoindentation regions. Taken from J. Martos M. A. Okuniewski R. J. Stromberg K.
