Telemark's New Model 862 Deposition Controller builds on the success of the model 861 controller and the 851 monitor, by adding co-deposition, crystal averaging and a larger screen. Developing advanced coatings has never been easier with the 862 co-deposition control, with functionality for crystal averaging for up to four sensors at one time. Using proven, innovative crystal oscillator design to provide outstanding stability and noise immunity, the Model 862 operates with either 5 MHz or 6 MHz crystals. The 862 includes an extensive library of over 300 materials and allows for user definable materials. The easy to read Color LCD touch screen for graphical and numerical display has an intuitive and user-friendly operator interface. The Touch screen capabilities include In-process parameter modifications; Process and Layer editors; I/O status and control.
After its long journey to Mars beginning this summer, NASA’s Perseverance rover will be powered across the planet’s surface in part by plutonium produced at the Department of Energy’s Oak Ridge National Laboratory. “Mars 2020 will be the first NASA mission that uses ORNL-produced plutonium-238,” said Alan Icenhour, associate laboratory director for nuclear science and engineering at ORNL. “This accomplishment represents countless hours of work by dedicated ORNL staff, and it’s rewarding to see this work come to fruition. Helping NASA in its mission to Mars is a significant moment in the history of the lab.”
Pfeiffer Vacuum has been setting standards in vacuum technology for 130 years. Science and industry have benefited equally from the numerous innovations developed and successfully brought to the market by this long-established company. The best example of this is the turbomolecular pump, which was developed by the company in 1958 and has been indispensable in the market ever since. Thanks to its expertise, Pfeiffer Vacuum is still the world market and technology leader in this field.
If you want to research historical events for a college essay, learn about tropical fish, or even translate text into a different language, you can type keywords into an internet search engine and get almost instant results drawn from diverse, international sources on that subject. Unfortunately, it’s not so easy for the scientist trying to find solutions for the COVID-19 pandemic. Even though researchers across the world have already amassed a wealth of information about the disease and continue to reveal new insights every day, this valuable data is stored in different digital libraries, organized in different structures, and written with different jargon. To get the most out of our collective COVID-19 knowledge, someone needs to collect it all in one place. And that’s precisely what a team led by Lawrence Berkeley National Laboratory (Berkeley Lab) is doing. Under a special project launched in May, computing and bioinformatics experts are working together to develop a platform that consolidates disparate COVID-19 data sources and uses the unified library to make predictions – about potential drug targets, for example.
Since 2000 Vacuum Technology & Coating Magazine has been the industry's leading source for the latest articles, news, and product and service information. Below we describe some of the terms that you will find in a typical issue of VT&C.
Vacuum Coating (Vacuum Deposition and Thin Film Deposition) is the process of depositing a film or other material atom by atom or molecule by molecule onto a surface in a low pressure environment or vacuum.
Physical Vapor Deposition or PVD refers to vacuum deposition methods which involve the material (which is being deposited) going from a condensed phase to a vapor phase and then to a thin film condensed phase. Sputtering and evaporation are common PVD processes.
Sputtering refers to a type of process used to deposit thin films and employs a plasma to bombard and eject atoms from a target source.
Evaporation refers to the heated source material being evaporated in a vacuum. Vacuum allows vapor particles to travel directly to the target object, where they condense back to a solid state. (called a Deposition Source) refers to a type of process used to deposit thin films and employs a plasma to bombard and eject atoms from the target source (called a Deposition Source).
Vacuum Hardware refers to the types of hardware and components that are used in the vacuum process. There are many types of hardware used in this process, some examples are flanges, fittings, seals, valves, and chambers.
Thin Film Metrology involves determining the optimal thickness, composition and/or condition of a coating through various techniques and mathematical calculations.
Gas Analytical Systems are used in the analysis of residual gases within a low pressure environment or vacuum.
Vacuum Pumps are devices that remove gas atoms and molecules for the purpose of leaving behind a partial vacuum. Some examples of types of vacuum pumps are rotary vane pumps, diaphragm pumps, and scroll pumps.
Every issue of VT&C includes a product showcase focused on a specific topic relevant to Vacuum Processing, please see our editorial calendar which lists the topic for each issue.
