VACUUM SCIENCE BLOG

When working with high vacuum (HV) and ultra-high vacuum (UHV), there are specific aspects to consider to ensure an efficient and safe system.

To clarify, the pressure range of UHV conditions are defined as between 10-7 and 10-12 mbar, whereas HV conditions are defined as between 10-3 and 10-7 mbar. Some of the main applications of HV include metallurgical processes, nuclear physics, space simulation and analytical instruments. On the other hand, UHVs are used for surface analysis, in high-energy physics and Molecular Beam Epitaxy (MBE). 

In this blog, we discuss the four main considerations you need to bear in mind when working under HV or UHV conditions.

Vacuum can never be completely appreciated unless it is fully known, and I've always noticed that those who work in the vacuum industry have a genuine commitment to their passion in vacuum science and a willingness to apply it to a range of scenarios.

Dr Graham Rogers unpacks the critical role that vacuum technology plays in the production, storage and transport of COVID-19 vaccines.

In this blog post, I break down what you can expect from the book in each of its major sections, and offer suggestions on how it can best add value as part of your regular research and development routine.

In our blog: 'Introduction to Vacuum Coating Technology', we introduced you to various PVD (Physical Vapor Deposition) methods and how products are typically coated using vacuum technology. Then, in our second blog 'Introduction to Vacuum Coating by Thermal Evaporation', we focused on coating techniques and applications using thermal evaporators and e-beam-evaporators. This blog, will introduce you to sputter technologies, typical uses, and how vacuum technology is applied to the process.

Many vacuum conferences scheduled for 2020 were either cancelled, postponed to 2021, or shifted online. Unfortunately, we’re still in the grips of the COVID-19 pandemic, and even conferences postponed by a full year are facing further postponement or cancellation.

Here’s a quick status update on some of the most important conferences related to vacuum technology and its applications:

In this blog post, we share some recent installations of UHV/XHV pump technologies in electron synchrotrons and how these special pumps perform.

Fore vacuum pumps are defined as those which exhaust to atmospheric pressure. They are also required to support secondary pumps or to attain the initial conditions for their operation. There are two types of fore vacuum pumps:

The storage and transport of COVID-19 vaccines has to be managed in a cold chain, with the first approved vaccine by Pfizer-BioNtech requiring storage temperatures of -70 C. Besides using dry ice (solid carbon dioxide at -75.8 C), Vacuum Insulated Panels and vacuum insulation have become attractive solutions.
