Used GATAN 894 #293659675 for sale

GATAN 894 is a dedicated ion milling equipment used to replicate, smooth and thin specimen surfaces. It utilises ion-bombardment milling techniques, creating surfaces that have good topographical and surface finish characteristics. This system is ideal for metal etching, creating electron transparent samples, adhesion and wetting control, and the creation of metal and polymer thin films. 894 consists of a number of components, including an ion source, a beam shutter unit, a gas control unit, a gun head and sample chamber, and a vacuum unit. The ion source is a noble gas-filled ion gun, capable of regulating the amount of ions being released and the beam shutter unit allows for micro-fabrication of nanoscale features. The gas control unit facilitates the broad range of gases that can used with the ion gun and the gun head and sample chamber provide a space for the sample to be worked on. The vacuum machine is critical to ensure an operating pressure of roughly 10-6 mbar, which is necessary for noble ions to strike the sample. The ion bombardment functions by harshly pelting the sample with positively charged noble gas ions. This manner of milling removes material from the sample surface and creates a smooth, polished surface. The environment at the sample surface can be changed by modifying the pressure, type of gas, current and angle of the gun. All of these parameters can be precisely set within the tool due to its digital control. GATAN 894 also offers a range of different milling modes and settings, including low angle ion beam-assisted growth, ion beam-assisted crystallization, layer-by-layer etching and polymer lift-off. Additionally, the software can simulate the created sample surface before any milling is actually done. This allows for the user to check and assess the milling parameters before any real time etching of the sample occurs. In conclusion, 894 is an ion milling asset specifically designed to refine and thin sample surfaces. It comes with a range of components as well as a range of different milling modes, settings and simulations. All of these facilities allow users to produce samples with excellent topographical characteristics.
