While studying preparation techniques for these thin lamellae, factors to be considered include the class of the material being polished, and whether the technique is repeatable when applied across a range of samples. In this article, broad argon beam milling and focused ion beam milling (FIB) are discussed.
of a silicone rubber sample after cross-section milling at room temperature (a) and under cooled conditions (b). Note the presence of wrinkles in the room-temperature cross-section milled sample in regions where the rubber parent material is present; these are due to the increased temperatures produced by argon ion beam irradiation. In contrast,
milling etching two approaches are exploited. The first one is to vary the incident angle of the Argon-etching beam with the sample, removing by etching part of the redeposited material gather on the sidewalls. The angle between beam and sample surface ranges from 40¼-90¼.
For example: stand-alone, specialized, broad-beam, argon polishers are currently a typical component of a high-quality transmission electron microscopy (TEM) sample prep workflow. With the Helios Hydra DualBeam, the focused argon beam can be applied to the sample directly after initial milling, vastly reducing transfer and processing time for ...
In this work we examine how microstructures can be reconstructed in three-dimensions (3D) by serial argon broad ion beam (BIB) milling, enabling much larger volumes (>250×250×100µm 3) to be acquired than by serial section focused ion beam-scanning electron microscopy (FIB-SEM).. The associated low level of damage introduced makes BIB milling very well suited to 3D-EBSD acquisition with very ...
During milling, the sample is rocked automatically to avoid creating beam striations on the cross sectioned surface. Due to the glancing incidence of the ion beam, argon is not implanted into the sample surface. Cooling Cross Section Polisher with Air Isolation

Ion beam milling with the scia Mill 200 uses argon ions to physically remove the magnetic layers. The ion beam source fabricated by scia Systems allows a precise tuning of the ion density and ion energy. Due to the ion bombardment, the argon ion beam milling allows the removal of all materials used in the TMR stack in contrast to chemical etching.

and 2 kV, broad-beam argon ion milling achieved a mean KAM of 0.04, which is close to the reference Si EBSD calibration standard. Sample preparations at 4 kV and 2 kV were also characterized by a very narrow KAM distribution when compared to the 2 hours colloidal silica mechanical polishing finish.
Ion milling machine thins samples until they are transparent to electrons by firing ions (typically argon) at the surface from an angle and sputtering material from the surface. By making a sample electron transparent, it can be imaged and characterized in a transmission electron microscope (TEM). Ion beam milling may also be used for cross-section polishing prior to SEM analysis of materials ...
Types Krypton laser. A krypton laser is an ion laser using ions of the noble gas krypton as its gain medium.The laser pumping is done by an electrical discharge.Krypton lasers are widely used in scientific research, and in commercial uses, when the krypton is mixed with argon, it creates a "white-light" lasers, useful for laser light shows.
Figure 3 shows a schematic view of flat milling. In flat milling methods, an argon ion beam impinges on the sample surface at an angle and the axis of the beam is deflected from the sample rotation axis to allow processing of a wide sample area 3). The incident angle θ of the argon ion beam may be varied over the range 0° - 90° 4). If θ is ...
