While vacuum electronic devices have largely been superseded over much of consumer electronics, there’s one place where they can still be found for now. The cavity magnetron is a power RF oscillator ...

Paul March indicates that Eagleworks NASA has started the build of their 1.2kW magnetron powered EM-Drive prototype in a tetter-totter balance system. It is being built to replicate the thrust ...

Jefferson Lab Senior SRF Accelerator Physicist Haipeng Wang displays the core of a cavity magnetron during an April 2024 lab tour. NEWPORT NEWS, VA - A pocket-size gizmo that puts the “pop” in ...

If one envisions the quantum vacuum (Q-V) as a semi-virtual electrical plasma as Dr. White does, that would imply that the Poynting power flow vector would entrain the Q-V plasma and send it on its ...

Vacuum tubes disappeared from electronic products years ago. Yet there have been some lingering vacuum tube-based products in production. Vacuum tubes disappeared from electronic products years ago.

A pocket-size gizmo that puts the "pop" in microwave popcorn could soon fuel particle accelerators of the future. The small but mighty device is a magnetron—a mashup of the words "magnetic" and ...
