Using the PIPS II system, the Ar ion beam is well focused at low energies (~1 mm FWHM). The current density at the milling area is also high, resulting in a high rate of material removal. Milling time should therefore be optimized to remove sufficient material to enhance sample quality without over-thinning the sample. tom price to karijini national park

"WebCryo-focused ion beam milling for MicroED. Thermo Scientific Cryo-FIBs/PFIBs perform ion-beam thinning of the crystals directly on the grid and the sample can remain there for subsequent diffraction analysis in the cryo-TEM.
