Abstract
마그네트론은 양극(1)과 음극을 포함하고, 상기 음극은 양극안에 설치되며, 표면에 정열된 제1 및 제2방출부품을 가진 막대(2)형태로 만들어졌다. 제1 방출부품은 견고한 초박막 금속으로 제작되고, 중심에 구멍을 가진 최소한 하나의 평면 디스크(3)형태로 만들어진다. 제2방출부품은 방출활성물질로 제작된 적어도 하나의 원통형 부시(4) 형태로 만들어진다. 디스크(3)의 외경은 0.1 내지 내부전극 간격값인 0.2 정도 부시(4)의 외경을 초과한다. 인접한 디스크(3) 및 부시(4)의 끝면은 서로 인접해 있다.The magnetron comprises a positive electrode 1 and a negative electrode, which is installed in the positive electrode and is made in the form of a rod 2 having first and second emitting parts arranged on the surface. The first release part is made of solid ultrathin metal and is made in the form of at least one flat disk 3 with a hole in the center. The second release part is made in the form of at least one cylindrical bush 4 made of a release active material. The outer diameter of the disk 3 exceeds the outer diameter of the bush 4 by about 0.2, which is an interval value between 0.1 and the inner electrode. The end faces of the adjacent disk 3 and the bush 4 are adjacent to each other.
본 발명은 예비적인 음극 가열없이 순간적으로 마그네트론을 점화하는 것이 가능하게 하며, 상기 순간점화가 가능한 것은 전기장 방출을 얻기 위해 요구되는 전기장 세기를 마그네트론을 여기하기에 충분한 값으로 제공하기 때문이다.The present invention makes it possible to ignite the magnetron instantaneously without preliminary cathodic heating, since the instantaneous ignition is possible because it provides the electric field strength required to obtain the electric field emission at a value sufficient to excite the magnetron.
