Vacuum arc cathode spots represent highly localised regions of intense plasma activity that occur on the electrode surface under high electrical stress in vacuum environments. These spots are ...

Vancouver Island artist Kyle Miller has found a new use for an old technology, using Soviet-era , cold cathode Nixie tubes to build displays for handmade, steampunk clocks. "The biggest appeal of a ...

Linear, small-signal AC models can be useful in the analysis and design of vacuum-tube-based circuits. Under large-signal conditions, nonlinear models are typically required. Almost 120 years ago, ...

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.
