We live in a world of solid-state active devices that have made most vacuum tubes obsolete, but a few types remain as they are still indispensable. The previous part of this article introduced the traveling wave tube and its basic operation, along with some attributes. This part delves into some related issues. Q: What’s the […]
Vacuum tubes we still (have to) use: The photomultiplier tube, Part 2
We live in a world of solid-state active devices that have made most vacuum tubes obsolete, but a few types remain as they are still indispensable. Part 1 of this article explained the basics of the photomultiplier tube. This part looks into other PMT characteristics. Q: Are there solid-state functional equivalents to the PMT? A: […]
Vacuum tubes we still (have to) use: The photomultiplier tube, Part 1
Maybe we can’t live with them, but we can’t live without them, at least not yet: the photomultiplier tube and the traveling wave tube are two vacuum electron-tube devices that are still viable and needed in our solid-state world.) It’s widely accepted conventional wisdom that almost “everything” has gone solid state and that vacuum tubes […]
Gallery: Neat tech on display at ADAS & Autonomous Vehicles USA
A focused forum on the here-and-now of self-driving technology held in Novi, Mich., staged by TU-Automotive, featured presentations by Tier 1 suppliers, researchers, and automakers. Also, there were a few displays of interesting technology. Here are a few examples of what was there to be seen. NEXT PAGE: A washer system for car cameras
