Ultra-high vacuum system for 3D atom probe device (3D-AP)
The position-sensitive atom probe (PoSAP), developed in 1988 by A. Cerezo and others at the University of Oxford, incorporates a position-sensitive detector into the atom probe's detection system, allowing for the simultaneous measurement of the flight time and position of atoms that reach the detector without using an aperture during analysis. This device not only enables the display of all constituent elements in an alloy present on the sample surface as a two-dimensional map with atomic-level spatial resolution, but it also allows for the extension of the two-dimensional map into a three-dimensional map by evaporating the sample surface one atomic layer at a time using the field evaporation phenomenon, thus enabling display and analysis in three dimensions.

Company information
The history of Kitano Seiki is also a trajectory of continuous contribution to cutting-edge research fields through the provision of precision instruments for research and development. In November 1958, we were established as a company specializing in the design, manufacturing, and sales of precision instruments. Since then, we have developed and manufactured experimental equipment aimed at research institutes in universities and government agencies, as well as basic research laboratories in private companies, earning high praise for our excellent quality and reliability. In particular, in recent years, we have been at the forefront of ultra-high vacuum and ultra-low temperature technologies, which are essential in industrial fields such as new materials, nanotechnology, flat panel displays, high-temperature superconductivity, solar cells, nuclear power, and space development. We have accumulated abundant technology and know-how in creating experimental environments and have linked this to the development and provision of equipment that condenses advanced performance and functionality. At Kitano Seiki, we always work closely with researchers, our users, to design and develop equipment that accurately supports research and development objectives. With a consistent system from parts manufacturing to various processing, assembly, inspection and testing, equipment setup, and after-sales support, we provide high-quality products and a conducive experimental environment for quality research and development.
