Used GATAN 691 #293757339 for sale

GATAN 691 is an ion milling equipment that is used to remove material from a surface in a localized manner without causing any substantial topographical modification or damage to underlying surfaces. The system consists of a high voltage source, a vacuum chamber, an ion milling tool, and various other components designed to reduce the risk of damage to the substrate. Ion milling is an abrasive process where ions are accelerated to strike the material surface causing material displacement and/or layer ablation. 691 unit has a relatively small vacuum chamber which measures approximately 16 inches in diameter. It is built around a stainless steel bellows and has an operational pressure of up to 10-6 torr. The machine is equipped with a high voltage source in the range of 1 to 25kV and a current supply of up to 20mA for the ion milling electrode. The ion milling gun has adjustable parameters to control the angular deviation, energy, and charge of the ions. The tool is also equipped with a shutter for controlling the exposure of the material surface to ions. The angular deviation of the ions is adjustable in the range of 0-9.9 mRad. This allows the precise location of the beam strike on the material surface. The adjustable energy and charge of the ions can be used to select the depth at which material removal occurs. This is useful in avoiding any significant topographical changes in the underlying substrate. GATAN 691 asset can be used to process a variety of materials. Suitable materials for ion milling include Al, Cu, Ti, Si, Ge, and Ni aluminum alloys. The model is also equipped with a container for collecting the ablated material and debris generated during the ion milling process. 691 equipment is often used in the fabrication of semiconductor substrates, thin film deposition systems, carbon films, and gallium arsenide components. It has several advantages including precise material removal, minimal substrate damage, and increased throughput. Ion milling systems, such as GATAN 691, allow researchers to accurately control the depth and location of material removal, and create intricate patterns and features in a variety of materials. The system is reliable and can be used to fabricate components to precise specifications. In summary, 691 is a highly reliable ion milling unit with adjustable parameters that allow precise material removal for a variety of applications.
