What is Nuclear Fusion? And How Does it Work?

Aligning with recent breakthroughs in the field, nuclear fusion is being increasingly discussed in the media. But what is nuclear fusion and how does it differ from nuclear fission? And why are so many companies and states investing in fusion research and development? 

We answer these questions here before highlighting the enabling role that vacuum plays in achieving nuclear fusion.

Ultra-high Vacuum Fittings: What Are Flanges Used For?

Despite how commonplace vacuum technology is, it can be difficult to know what fittings and parts are needed to create ideal vacuum environments. Here, we explore what vacuum flanges are and what they may be used for. Let’s start by looking at how flanges are used to create vacuum systems.

What Are the 5 Signs of Vacuum Pump Failure?

Even the most well-constructed vacuum pump can fail after extended use. In industrial applications, for instance, the downtime resulting from pump failures can be prohibitively expensive — especially if it forces production to grind to a halt.

How Vacuum Technology Supports COVID-19 Vaccine Efficacy

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.

The key working principles of High and Ultra-High vacuum pumps

High Vacuum (HV) and Ultra-High Vacuum (UHV) levels can only be effectively and efficiently obtained by using a main pump that has the functional capabilities. Choosing which pump to use depends on a number of factors, such as noise/vibration, cost (initial and on-going), tolerance to contamination, footprint, maintenance schedules, and resilience to shock.
