Thermal gauges, out of all the available gauge technologies, offer excellent value for measuring rough vacuum pressure, but even UHV and XHV systems can benefit from them. All thermal gauges operate by heating a filament and exposing it to the vacuum…
When detecting leaks, it is important to distinguish between virtual and real ones. Examples of virtual leaks can be: gas desorption, diffusion, trapped volume, and back streaming. Leak-up or rate-of-rise tests can indicate whether a vacuum system's base…
Ionization gauges convert residual molecules to positively charged ions, and then attract them to a negatively charged collector where they create a measurable current. Modifications to high vacuum ionization gauges can optimize their performance at a…
No one gauge technology will provide pressure measurement throughout the range of vacuum. Combining vacuum sensors can produce a gauge capable of measuring pressure better than with any single technology. After having highlighted the properties of individual…
When choosing a vacuum gauge, it is possible to adopt high vacuum ionization gauges or sputter ion current. After describing the basic operating principle of the Sputter ion pump, this video shows how to measure UHV pressure with Agilent SIPs.
Material preparation and cleaning in ion pump manufacturing is critical to achieving ultrahigh vacuum pressures. One cleaning process to which the pump components are subjected is vacuum firing, through which the outgassing rate of the pump is reduced…
