Used GATAN 691 #293619345 for sale

GATAN 691 is an ion milling equipment used for surface preparation and nano-scale modification of sample surfaces. The system is a vacuum chamber which houses radio frequency (RF) capacitors and a beam shaping magnet, providing precise control of the orientation of the charged ion beam. 691 unit uses energetic ions for the milling process, which removes normal and soft materials at a nanoscale. This is done in three stages; an initial cleaning process of ions, mainly Argon, is used to get rid of any lubricant/contaminants that may have adhered to the sample; then an etching step is used to create nanoscale features in the material; and a final annealing sequence is associated with the ion beam, which is used to repair any surface damage caused by the earlier etching process. The machine has a computer-controlled vacuum-controlled chamber, along with a multi-axis goniometer, which provide a precise control of the rotation and tilt of sample surfaces. The goniometer is used to position the sample for in-situ imaging and for precise placement and adjustment to achieve desired milling results. In addition, the tool has a beamline/detector/filter arrangement, which can be tailored to the specific application. With its high ion current ranges up to 200 mA, GATAN 691 is ideal for use in a variety of applications such as device fabrication, nanostructuring, thin film deposition and sample preparation. It is suitable for irradiation with positive ions such as argon, xenon and carbon, as well as up to 6 keV electron beams. 691 offers a highly user-friendly and intuitive interface, making operation easy and efficient. It is designed with features that enhance performance and reliability, such as automatic alignment of the entire asset, and power-off protection. Its built-in interlock limits its operation to those who are properly trained and certified to use it. Additionally, the model can be configured with additional features such as precise laser interferometry and multiple-axis motors, to further ensure precise results. GATAN 691 equipment is highly efficient, providing superior quality results and surface modification at a reduced cost. It is also highly precise and flexible, allowing for specific process control and reliable results. This system is ideal for those looking for an advanced ion milling unit for precise and precise expertise surface preparation and nano-scale modification.
