IGM401 Hornet is InstruTech’s miniature hot cathode Bayard-Alpert ionization vacuum gauge module with a built-in controller and display. The pressure measurement range of the IGM401 is 1.00E-09 to 5.00E-02 Torr.
We supply many of the most commonly used vacuum pressure gauges including, Bayard Alpert glass and nude gauges, UHV nude gauges, Convection gauges, Piriani gauges, and Thermocouple gauges. All of our vacuum measurement gauges are identical to or functionally equivalent to the competitive tubes listed. Gauges are stock items and we offer competitive pricing
The semiconductor industry has made remarkable progress in recent years, leading to the development of ever smaller and more powerful chips. However, these advancements would not have been possible without a clean room powered by an efficient subfab.
Scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory have discovered new details about the electrons in a nickel-based family of superconducting materials. The research, described in two papers published in Physical Review X, reveals that these nickel-based materials have certain similarities with—and key differences from—copper-based superconductors. Comparing the two kinds of “high-temperature” superconductors may help scientists zero in on key features essential for these materials’ remarkable ability to carry electrical current without losing energy as heat.
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.
