Crookes tube
A Crookes tube: light and dark. Electrons (cathode rays) travel in straight lines from the cathode (left), as shown by the shadow cast by the metal Maltese cross on the fluorescence of the righthand glass wall of the tube. The anode is the electrode at the bottom. A Crookes tube (also Crookes-Hittorf tube) is an early experimental electrical discharge tube, with partial vacuum, invented by ...
William Crookes
Sir William Crookes OM FRS (/ k r ʊ k s /; 17 June 1832 - 4 April 1919) was a British chemist and physicist who attended the Royal College of Chemistry, now part of Imperial College London, and worked on spectroscopy.He was a pioneer of vacuum tubes, inventing the Crookes tube which was made in 1875. This was a foundational discovery that eventually changed the whole of chemistry and physics.
Sir William Crookes
Sir William Crookes (born June 17, 1832, London, Eng.—died April 4, 1919, London) was a British chemist and physicist noted for his discovery of the element thallium and for his cathode-ray studies, fundamental in the development of atomic physics.. After studying at the Royal College of Chemistry, London, Crookes became superintendent of the meteorological department at Radcliffe ...
Crookes Tube
Learn about the Crookes tube, a vacuum-sealed glass container that glowed fluorescent green when electricity was passed through it. Discover how this invention led to the discovery of the electron and the X-ray machine.
4.11: Cathode Ray Tube
Further Research with the Crookes Tube. Crookes' work opened the door to a number of important discoveries. Other scientists were able to demonstrate that the "cathode ray" was actually a stream of electrons.In 1897, Karl Ferdinand Braun developed the first oscilloscope, using a cathode ray tube to see an electrical pulse as it passed through the instrument.
Cathode Ray Tube Experiments
The term Crookes tube is also used for the first generation, cold cathode X-ray tubes, which evolved from the experimental Crookes tubes and were used until about 1920. The picture below illustrates the operation of a Crookes tube in a schematic way. For experiments with cathode ray tube we used an educational model readily available on eBay.

William Crookes. English scientist William Crookes was very innovative in his investigations with vacuum tubes and designed a variety of different types to be used in his experimental work. William Crookes was born in London, England, on June 17, 1832, the son of Joseph Crookes and his second wife, Mary Scott. At the age of 15, Crookes enrolled ...
Crookes' Tube
A solid object placed in the path of the cathode rays casts a shadow on the wall of the tube across from the cathode. The cathode rays also can be deflected by an electric field in a direction which suggests they are negatively charged. Contributors. Dr. George Bodner (Perdue University) Crookes' Tube.

William Crookes. The definitive experiments with cathode-ray tubes were done by William Crookes in 1879. Crookes' major contribution was the development of a better vacuum pump that allowed him to produce cathode-ray tubes with a smaller residual gas pressure. Crookes not only confirmed the previous work by Plucker, Hittorf, and others, he was ...
Sir William Crookes and the Fundamentals of Luminescence
Learn about the life and achievements of Sir William Crookes, a British physicist, chemist, and parapsychologist who discovered thallium, cathode rays, and luminescence. Find out how he used spectral analysis, radiometers, and Crookes tubes to explore the fourth state of matter and radioactivity.
Crookes Tube (ca. late 1800s)
Crookes Tube (ca. late 1800s) This is the classic version of what is often known as a Crookes tube. Developed by William Crookes to investigate electrical discharges in gas. Although it is not certain what type of tube Rontgen was using when he discovered X-rays, this is the type of tube most commonly assumed to be involved.

Discovery of the electron and nucleus (article)
The experiment for canal rays was carried out in modified cathode ray tube, by E. Goldstein.:: some properties of anode rays: 1. The positively charged particles depend upon the nature of gas present in the cathode ray tube. Those are simply the positively charged gaseous ions. 2. The charge to mass ratio of particles depends on the gas from ...

Two of Crookes's experiments are still sometimes used as demonstrations. Using a pear-shaped evacuated tube in which a Maltese cross made of mica was placed Crookes showed that when the current was switched on a clear black shadow was seen in showing that the cathode rays travelled in straight lines (Brock, 1971, p. 477).

3.1: Electricity and the Atom
The cathode ray tube was first invented by Sir William Crookes. Experiments showed that the rays had mass. Thomson's cathode ray tube showed that atoms contain small, negatively charged particles called electrons. Millikan discovered that there is a fundamental electric charge—the charge of an electron.
