Overview Equipment and Technology

In essence, an ion beam source is a plasma source having a set of grids that enable extraction of a stream of ions. The three main parts of the ion beam source are the discharge chamber, the grids and the neutraliser. Ion production is done in the discharge chamber by subjecting a gas like argon to an RF field.

Types of laser - SlideShare

Ion Laser: Argon Ion Laser All ion lasers (such as argon, Krypton and mix gas) produce several different wavelengths so they are designed to produce these wavelengths either simultaneously or individually. Argon lasers are generally operated in continuous wave mode. For argon lasers the output power can ranges from few mill watts up to 20 watts.

Ion Beam Polishing of Sample Surfaces - Leica Microsystems

Ion milling can be used to reduce the roughness of sample surfaces. Small angles less than 6° with respect to the sample surface are necessary. The high voltage depends on the material to be prepared. The reason for the levelling effect is the different milling angle of flat and rough surface areas. The milling rate is lower for small angles.
