If you work on simple digital projects, just about any bench supply will offer the voltage and current you’re looking for. However, if you’re working with valves, you’ll often find yourself needing ...

FOR many years the literature of applied physics has lacked a really up-to-date and complete account of the phenomena occurring inside valves. In consequence, students are taught very little about ...

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in ...

OAKLAND, CA, UNITED STATES, July 9, 2025 /EINPresswire.com/ -- Ray Tubes is pleased to announce that its new-production vacuum tubes are now available through its ...

New York Yankees slugger Aaron Judge and Los Angeles Dodgers superstar Shohei Ohtani are the leading vote-getters in the first round of MLB All-Star Game voting released Monday. Judge has received ...

Talking about vacuum tubes in 2025 might seem like talking about the role of buggy whips in today’s transportation world; but that’s not the case. There’s no denying that these devices—called vacuum ...

The video explains the operation of the vacuum tube, specifically the triode, which is essential in modern communication devices like radios and telephones. It describes how a tungsten filament emits ...

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, ...

Given appropriate models for vacuum tubes, circuit simulators such as SPICE make analysis based on such nonlinear models a tractable effort. The Langmuir, Leach, and Koren models are discussed for the ...

Networking: Liang Jiang reviews the proposed quantum network using vacuum beam guides, which would have ranges of thousands of kilometers and capacities of 10 trillion qubits per second. (Courtesy: ...
