The gas inside the tube is probably argon. We should probably not exceed 100 V on the deflecting plates. The Xantrex power supply is only rated to 60 V, so it should be fine. A more user-friendly ...
Say, about 150 years. Yes, that’ll do. A Crookes tube, the original electron beam-forming vacuum tube of glass, invented by Sir William Crookes et al. in the late 19th century, is what you need.
Photograph of a discharge tube of the type introduced by Sir William Crookes and one of the earliest types of x-ray tube, c.1896, originally part of the Tabor Collection. They were purchased at ...
Photograph of two discharge tubes containing a chemical substance used for experimenting on the effects of cathode rays on this substance. They were acquired by the Wellcome Historical Medical Museum ...
Object Details Description (Brief) Crookes Ray of Light High Vacuum Tube, unmarked, 2 electrodes including a flat circular cathode at end opposite potash bulb extension. 6" long internal metallic ...
When a sheet coated with keton was held close to the window of the modified Crookes tube, it produced a glow, demonstrating that cathode rays were able to travel a short distance through the air.
Professor Trowbridge's experiments with the cathode rays at the Jefferson Physical Laboratory have shown that the quality of glass constituting the Crookes tubes has very little to do with the ...
One of those was his invention of the cathode-ray tube, also known as the Braun’s tube. In an elegant paper published on February 15, 1897, Braun described the design and realisation of this tube.
