    • PURPOSE: A mobile type electron accelerator is provided to prevent radiation leakage by projecting an electronic beam accelerating from the high voltage generator to a reaction chamber. CONSTITUTION: A container is loaded on a trailer. A radiation shielding room(30) having a door set(40) is formed inside the container. The high voltage generator(50) accelerates the electronic beam. A beam projector outputs the electronic beam to a radiation shielding room in a vacuum condition. A cooling device(84) cools a high voltage generator, a beam projector, and a beam catcher. The gas supply unit supplies the insulation gas to the high voltage generator. An ozone adsorbent(88) adsorbs the ozone created in the reaction chamber. The controller(89) controls the power supply and the cooling device.

    • A vacuum tube electron beam device having a thin, single crystal, electron permeable, gas impermeable membrane for electron transmission and methods for making such a device. Single crystal membranes can have small thickness due to high strength, are highly transmissive to free electrons due to that small thickness. The ordered crystalline structure of such membranes provides minimal obstructions to electron beams, and yet is highly impermeable to penetration by gas and liquid molecules. Single crystals are anisotropically etched to precise membrane dimensions, and can also be etched to provide microchannel structures for flowing cooling fluid across the membrane during use. A doped silicon anode can provide support for the membrane with matching thermal expansion characteristics, and a crystalline anode can be integral with the membrane. A double membrane embodiment confines the cooling fluid so that it passes close to both membranes. A double membrane structure can also have a pressure between the membranes that is between the pressure within the vacuum tube and ambient pressure outside the vacuum tube, allowing the membranes to be thinner. The membrane can also be compressed for increased strength. A number of cooling methods are used to maintain the integrity of the membrane.
    • 一种真空管电子束装置,其具有用于电子传输的薄的单晶电子可渗透的不透气膜和用于制造这种装置的方法。 由于高强度,单晶膜可以具有小厚度,由于该小厚度,单晶膜对高自由电子具有高度透射性。 这种膜的有序晶体结构对电子束提供了最小的阻碍,但对气体和液体分子的渗透却是高度不可渗透的。 单晶被各向异性地蚀刻至精确的膜尺寸,并且也可以被蚀刻以提供用于在使用期间使冷却流体流过膜的微通道结构。 掺杂的硅阳极可以为具有匹配的热膨胀特性的膜提供支撑,并且结晶阳极可以与膜一体化。 双膜实施例限制冷却流体,使其靠近两个膜。 双膜结构也可在膜之间具有介于真空管内的压力与真空管外的环境压力之间的压力,从而使膜更薄。 膜也可以被压缩以增加强度。 许多冷却方法用于维持膜的完整性。

    • PURPOSE: To keep crystal structure after a cathode is bonded to a member by keeping single crystal structure of a single crystal cathode even after joining, reducing structural, radiative ununiformity, and reducing work function on radiation face made of tantalum. CONSTITUTION: A single crystal cathode made of tantalum welded with laser is bonded to a filament. The single crystal cathode is not a true single crystal, a structure body has variation of ±1 degree, and does not have directionally slipped particles. As a result, the single crystal cathode has low structural uniformity, and high radiation characteristics, and a crystal face has a work function having only 2% or less variation. Sufficient uniformity usable as a thermoelectron cathode for projection electron lithography treatment the same as SCALPET can be obtained. As the radiation face of the single crystal cathode, (111) planes or (100) planes are used.
    • 目的:通过保持接合后的单晶阴极单晶结构将阴极接合到构件上后,保持晶体结构,降低了由钽制造的辐射面上的结构,辐射不均匀性和降低功函数。 构成:将由钽焊接的单晶阴极与激光焊接在一起。 单晶阴极不是真正的单晶,结构体具有±1度的变化,并且没有定向滑动的颗粒。 结果,单晶阴极具有低结构均匀性和高辐射特性,并且晶面具有仅2%或更小变化的功函数。 可以获得与SCALPET相同的用作投影电子光刻处理的热电子阴极的足够的均匀性。 作为单晶阴极的辐射面,使用(111)面或(100)面。
