- Many ingenious types of Crookes tubes were built to determine the properties of cathode rays ( see below ).
- The first true electronic vacuum tubes, invented in 1904, used this hot cathode technique, and they superseded Crookes tubes.
- He attempted to measure their velocity by the Doppler shift of spectral lines in the glow emitted by Crookes tubes.
- Historically, X-rays were discovered radiating from experimental discharge tubes called Crookes tubes invented by British physicist William Crookes and others.
- He covered the Hittorf-Crookes tube with the cardboard and attached electrodes to a Ruhmkorff coil to generate an electrostatic charge.
- As the medical and other uses of X-rays became apparent, workshops began to manufacture specialized Crookes tubes to produce X-rays.
- Induction coils were used to provide high voltage for early gas discharge and Crookes tubes and other high voltage research.
- By the 1870s better vacuum pumps enabled scientists to evacuate Geissler tubes to a higher vacuum; these were called Crookes tubes after William Crookes.
- Crookes tubes generated the electrons needed to create X-rays by ionization of the residual air in the tube, instead of a heated Pa ).
- The ionization method of creating cathode rays used in Crookes tubes is today only used in a few specialized gas discharge tubes such as krytrons.
- The ionization method of creating cathode rays used in Crookes tubes is today only used in a few specialized gas discharge tubes such as thyratrons.
- Workshops began making specialized versions of Crookes tubes for generating X-rays and these first-generation cold cathode or Crookes X-ray tubes were used until about 1920.
- In the mid-nineteenth century, Julius Pl�cker investigated the light emitted in discharge tubes ( Crookes tubes ) and the influence of magnetic fields on the glow.
- The medical applications of X-rays created the first practical use for Crookes tubes, and workshops began manufacturing specialized Crookes tubes to generate X-rays, the first X-ray tubes.
- The medical applications of X-rays created the first practical use for Crookes tubes, and workshops began manufacturing specialized Crookes tubes to generate X-rays, the first X-ray tubes.
- After R�ntgen identified the x-ray Tesla began making X-ray images of his own using high voltages and tubes of his own design, as well as Crookes tubes.
- Starting in 1888, Philipp Lenard, a student of Heinrich Hertz, conducted experiments to see whether cathode rays could pass out of the Crookes tube into the air.
- The discovery for which J . J . Thomson is best remembered was made after he installed parallel metal plates in a modified Crookes tube, downstream from the anode.
- The full details of the action in a Crookes tube are complicated, because it contains a nonequilibrium plasma of positively charged ions, electrons, and neutral atoms which are constantly interacting.
- As a result of his Crookes tube investigations, he showed that the rays produced by irradiating metals in a vacuum with ultraviolet light were similar in many respects to cathode rays.
