Used GATAN 691 #293753793 for sale

GATAN 691 is an ion milling equipment used primarily for polishing and fabrication of samples for electron microscopy. This system is equipped with a high-performance, ultra-high vacuum (UHV) horizontal ion source with 12 kV acceleration power and a multi-axis, closed loop, multi-zone ion beam control unit. It is comprised of an ion gun, a positioning machine, and special optics. The ion gun is composed of an ion source, an extraction tool, a beam focusing asset, and an ion beam deflection model. The ion source is used to produce ions of the desired type and energy and is typically a diode. The extraction equipment is responsible for extracting the ion beam from the ion source's plasma and adjusting its trajectory. The beam focusing system is used to control the resolution, direction, and intensity of the beam to ensure proper sample processing. Lastly, the beam deflection unit adjusts the beam's trajectory to ensure that it is aimed properly at the target. The positioning machine is responsible for controlling the angular and linear position of the sample relative to the ion beam. It consists of an X-Y stage, a tilt stage, and a multi-zone chamber. The X-Y stage allows the sample to be moved in the X and Y directions while the tilt stage can adjust the sample's orientation in the Z direction. The multi-zone chamber allows the sample to be manipulated while still maintaining a vacuum in the chamber. 691 tool also includes a special optics asset that ensures good imaging. The optics are responsible for directing the ion beam and for filtering out unwanted ions. The model utilizes both a rotating and a reflecting mirror equipment, which can be used to angle the beam in the desired direction. The optics can also be used to filter light energy and subatomic particles that can interfere with sample processing. GATAN 691 is an advanced ion milling system that can be used for fabrication processes, polishing processes, and analysis of the microstructures of samples. Its high throughput and precision make it an ideal tool for sample preparation and imaging applications.
