canal rays

Japanese: canal rays(英語表記)canalrays
canal rays

…German physicist Julius Plücker (1801-68) named the radiation emanating from a cathode as cathode rays, and through numerous experiments criticized W. Crookes' theory on these rays. In 1886, he used a cathode with a hole in it to discover that there was radiation that passed through the hole in the opposite direction to cathode rays, and gave the name canal rays to this type of anode ray. [Yutaka Kawamura] …

From [Anode Ray]

…It was named after the fact that it was discovered as a beam coming out of the anode when a vacuum discharge occurs. When a small hole (canal) is drilled in the cathode of a vacuum discharge tube and a discharge is made, the canal rays that come out through the small hole are also included in the anode rays. Canal rays were discovered by E. Goldstein in 1886, and it was later discovered that the gas inside the tube became positive ions due to the collision of an electron beam, and these were accelerated near the cathode to form a beam. …

…ドイツの物理学者プリュッカーJulius Plücker(1801‐68)が発見した陰極から発する放射線に対して陰極線の名を与え,数多くの実験を通してこの線に関するW.クルックスの説を批判した。さらに86年には,穴をあけた陰極を使用することによって,陰極線とは反対方向に穴をつき抜ける放射線があることを見いだし,陽極線の一種であるこの線にカナル線canal raysの名を与えた。【河村 豊】。…

【陽極線】より

…真空放電を起こしたとき陽極から出るビームとして発見されたのでこの名がある。真空放電管の陰極に小さな孔(canal)をあけて放電させたとき,その小孔を通って出てくるカナル線canal raysも陽極線に含める。カナル線は1886年E.ゴルトシュタインによって発見されたもので,その後管内の気体が電子線の衝突によって陽イオンとなり,それが陰極付近で加速されたビームであることが判明した。…
