    • An object of the present invention is to provide a sample holding unit for an electron beam apparatus which allows observation of a reaction between a sample and gas. In order to solve one of the above-stated problems, the present invention includes: electron beam apparatus sample holding means in which a diaphragm is placed on upper and lower sides of a sample to form a cell for separating a gas atmosphere and a vacuum atmosphere of a sample chamber and sealing an ambient atmosphere of the sample; a gas supply means for supplying gas to an inside of the cell; and exhaust means for exhausting gas. The exhaust means includes a gas exhaust pipe provided in the inside of the cell and an openable/closable exhaust hole provided in a sidewall of the sample holding means so as to pass through the cell. The diaphragm is an amorphous film made of light elements which can transmit an electron beam, such as carbon films, oxide films, and nitride films.
    • 本发明的目的是提供一种能够观察样品和气体之间的反应的电子束装置的样品保持单元。 为了解决上述问题之一,本发明包括:电子束装置样品保持装置,其中将膜片放置在样品的上侧和下侧以形成用于分离气体气氛的气室和真空气氛 的样品室并密封样品的环境气氛; 气体供应装置,用于将气体供应到电池内部; 以及用于排出气体的排气装置。 排气装置包括设置在电池内部的排气管和设置在样品保持装置的侧壁中以便通过电池的可开启/关闭的排气孔。 隔膜是由透光电子束如碳膜,氧化膜和氮化物膜的轻元素制成的非晶膜。

    • Apparatus for high-angle annular dark-field (HAADF) imaging without limiting the maximum tolerable pressure of gas introduced into the specimen chamber (7). The apparatus has an electron gun (2), a specimen chamber in which a specimen (5) is set, a gas cylinder (37) for supplying environmental gas to around the specimen surface through both a gas flow rate controller (39) and a gas nozzle (40), a vacuum pump (36) for evacuating the inside of the specimen chamber, an objective lens including upper and lower polepieces (8',9'), a detector (21,22,14,15) for detecting electrons transmitted through the specimen, a display device (19) for displaying a transmission image of the specimen based on the output signal from the detector, orifice plates (50) having minute holes (A-E), holders (51) supporting the orifice plates, a drive mechanism (52) for driving the holders, and a motion controller (53). The specimen is set between the upper and lower polepieces. The beam from the electron gun is transmitted through the objective lens. The orifice plates can be moved in a direction crossing the optical axis of the beam on the upper and lower surfaces of the upper and lower polepieces of the objective lens.
