Abstract: A core type magnetron comprising a vacuum envelope which includes an open ended magnetic anode cylindrical member and magnetic upper and lower end plates for closing the opposite end openings of the cylindrical member. Internal to the vacuum envelope, a plurality of anode vanes are provided which extend in a radial direction from the approximate middle of the inner wall of the cylindrical member toward the center of the envelope. A pair of permanent magnets provided internal to the envelope, each extending from opposite end plates toward the anode vanes. By this arrangement, an operating space is defined by the opposing surfaces of the pair of the magnets and the anode vanes, such that a magnetic flux is applied to said operating space. A cathode is provided within the operating space. The magnets employed are characterized as being low in the emission of gases during operation of the magnetron, since they are manufactured by a process which includes melting designated source materials mixed with a small amount of silicon in a vacuum, casting the melt in a vacuum, followed by forging.

Abstract: In a magnetron of the permanent-magnet-externally disposed-type wherein a pair of permanent magnets are disposed outside an anode cylinder, a yoke magnetically coupling the pair of permanent magnets to each other is extended along the side wall of an anode cylinder of the magnetron, and this anode cylinder is securely fixed to the yoke. The permanent magnets are each supported between the yoke and a seal plate for sealing the opening of the anode cylinder of the magnetron.

Abstract: The apparatus disclosed herein provides high energy positive ions, suitable for semiconductor doping, by projecting positive ions through an electron stripping gas at relatively low energy thereby to obtain positive ions which are multiply ionized or charged. Those ions which are raised to a preselected ionization level or state are segregated, and then accelerated by a relatively high accelerating voltage to achieve an energy suitable for ion implantation in a semiconductor matrix. Since the ions subjected to the relatively high accelerating voltage are multiply ionized, the energy imparted thereto, measured in electron volts, is substantially equal to an integer multiple of the accelerating voltage.

Abstract translation: 本文公开的装置通过以相对低的能量将正离子投射通过电子剥离气体来提供适合于半导体掺杂的高能正离子，从而获得多重电离或带电的正离子。 升高到预选电离水平或状态的那些离子被分离，然后通过相对高的加速电压加速，以获得适合于半导体基质中的离子注入的能量。 由于经受相对高的加速电压的离子被多次电离，所以以电子伏特测量的赋予的能量基本上等于加速电压的整数倍。
