We hope you enjoyed this look back at the last 100 years of television in science. From the early days of physicists ...

Some people might be worried, or at least wondering, about whether their old CRT TV emits harmful radiation. Here's what you need to know.

In this video, we explore cathode rays, the science behind super-fast electrons, and how they lead to the discovery of X-rays. We break down the history, physics, and applications of these phenomena, ...

Abstract: In this study, a compact high-frequency pulsed X-ray tube based on carbon nanotube (CNT) field emission was developed. A high-adhesion CNT cathode electron emitter was fabricated using an ...

Do you have experience with vacuum tubes? Help us analyze a Heathkit oscilloscope schematic and compare it to what AI told me. Figure 1. The front panel of a Heathkit OI-10 oscilloscope uses banana ...

Sandia scientists developed a new type of X-ray that uses patterned multi-metal targets to create colorized, high-resolution images. The technology promises sharper scans, better material detection, ...

New research by scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab), in collaboration with scientists from TAU Systems Inc., has brought the promise of ...

A new retro gaming monitor is currently being crowd-funded, and it's designed to push the nostalgia buttons of anyone who remembers the days of CRT screens. Sadly, there isn't an actual cathode ray ...
