During 1895 and 1896, in a scientific atmosphere enriched by reports of the discovery of x rays and becquerel rays or radioactivity, thomson brought the study of cathode rays into his research on electricity and gases. He had studied cathode rays previously, trying to provide a theoretical framework to describe the rays.

1) with slits in them are placed in a bulb connected with the discharge-tube; the cathode rays from the cathode a pass into the bulb through a slit in a metal plug.
Cathode rays these rays, like light, traveled in a straight line, cast shadows of obstacles, but unlike light could be bent by electric and magnetic fields. It was thus clear that these rays consisted of charged particles.

Apr 16, 2018 a cathode ray is a beam of electrons that travel from the negatively charged to positively charged end of a vacuum tube, across a voltage.
Indeed, in 1876, the german physicist eugen goldstein (1850-1930) named the flow cathode rays. It seemed natural to suspect that the cathode rays might be a form of light, and be made up of waves. Waves traveled in straight lines, like light, and, like light, seemed unaffected by gravity.
Electron by examining the early history of experiments 1897 experiment on cathode rays, which is celebrated this year as the flash when a rifle is fired.
How cathode rays works the electrode at the negative end is called a cathode. Since electrons are repelled by the negative charge, the cathode is seen as the source of the cathode ray in the vacuum chamber.
Thomson's electron presents the compelling story of the discovery of the electron and its role as the first subatomic particle in nature.
In 1869 he ascertained that the cathode rays glowed different colours because of different gasses and pressures. He noticed that when there was any object placed between the cathode and the illuminating side of the tube, then the shadow of that object appeared. His work led toward development of x-rays and cathode ray tubes.
Fundamental studies of a repetitive flash x-ray generator using a disk-cathode radiation tube are described.
When the cathode rays (whose path was traced by the phosphorescence on the glass) did not fall on the slit, the electrical charge sent to the electrometer when the induction coil producing the rays was set in action was small and irregular; when, however, the rays were bent by a magnet so as to fall on the slit there was a large charge of negative electricity sent to the electrometer.
The detection of cathode rays was a by-product of the investigation of the discharge of electricity through rarefied gases. The latter phenomenon had been studied since the early eighteenth century.

Thompson concluded that cathode rays are a new type of negatively charged matter called an electron. Sir william crookes, an early pioneer of the crookes tube, later called a cathode ray tube the discovery of x-rays, and the birth of modern medical.
Cathode rays (also called an electron beam or an e-beam) are streams of electrons observed in vacuum tubes. If an evacuated glass tube is equipped with two electrodes and a voltage is applied, the glass opposite the negative electrode is observed to glow from electrons emitted from the cathode.
Johann heinrich wilhelm geißler (26 may 1814 in igelshieb – 24 january 1879) was a skilled glassblower and physicist, famous for his invention of the geissler tube, made of glass and used as a low pressure gas-discharge tube.
Johann wilhelm hittorf (27 march 1824 – 28 november 1914) was a german physicist who was born in bonn and died in münster, germany. Hittorf was the first to compute the electricity-carrying capacity of charged atoms and molecules (), an important factor in understanding electrochemical reactions.
Johann hittorf discovered cathode rays in 1869 using a crookes tube and noting shadows cast on the glowing wall of the tube opposite of the cathode. Thomson discovered that the mass of the particles in cathode rays was 1800 times lighter than hydrogen, the lightest element.
Starting from the investigations of cathode rays in germany, france and mainly england, the successful path of j j is covered in some detail using available information (letters, notebooks, diaries, publications), as well as his later work on positive rays and the atomic model.
