In electron holography observation using a transmission electron microscope, searching of conditions of an electron optical condition which are necessary for realizing a requested spatial resolution is sophisticated and for persons unaccustomed to operation of the electron microscope, the observation is time consuming work. In addition to the fundamental electron microscope proper, an input unit for inputting a spatial resolution requested in the holography observation, a calculation unit for calculating positions of electron biprism and specimen necessary for realizing the requested spatial resolution from the inputted value and parameters characteristic of the device and mechanisms for moving the two positions for realizing the obtained calculation results are provided.

An electron beam observation device includes a mechanism which disposes a specimen at an upstream side in an electron beam traveling direction outside an objective lens, from which an image is transferred under a magnification of ⅕ to 1/30, in addition to an inside of the objective lens in which a specimen is disposed at a time of ordinary observation.

A multi-biprism electron interferometer is configured so as to arrange a plurality of biprisms in an imaging optical system of a specimen. This generally requires a plurality of ports for the electron biprisms in a magnifying optical system from an objective lens onward and also requires electromagnetic lenses, which are combined with the respective electron biprisms and operated in association therewith, to provide the interference optical system with a degree of freedom. As a result, not only the electron biprism ports but also electromagnetic lenses need to be additionally configured in the imaging optical system of a conventional electron microscope so as to display the performance as the multi-biprism electron interferometer. The present invention arranges an upper electron biprism upstream of the specimen in the traveling direction of the electron beam and forms an image of the electron biprism on the specimen (object plane) using an imaging action of a pre-field of the objective lens. A double-biprism interference optical system is constructed of a lower electron biprism disposed downstream of the objective lens up to the first image plane of the specimen. No new electromagnetic lens needs to be added in this optical system.

A transmission electron microscope has a means for inputting a spatial size or distance d desired to be observed by the operator, calculates high contrast of an image based on this value and an observing condition which can reduce the influence of a false image superimposed, and desirably modulates an accelerating voltage of the electron microscope based thereon.

摘要:
There is a limit in range and distance in which an electron beam can interfere and electron interference is implemented within a range of a coherence length. Therefore, interference images are consecutively recorded for each interference region width from an interference image of a reference wave and an observation region adjacent to the reference wave by considering that a phase distribution regenerated and observed by an interference microscopy is a differential between phase distributions of two waves used for interference and a differential image between phase distributions of a predetermined observation region and a predetermined reference wave is acquired by acquiring integrating phase distributions acquired by individually regenerating the interference images. This work enables a wide range of interference image which is more than a coherence length by arranging phase distribution images performed and acquired in the respective phase distributions in a predetermined order.

[Object] To provide a heat transport device manufacturing method and a heat transport device that has a high hermeticity and is manufactured without increasing a load applied at a time of performing diffusion bonding.[Solving Means] A bonding surface (1a) of an upper member (1) that is subjected to diffusion bonding to a bonding surface (21) of a frame member (2) is formed into a convex shape, which can make a contact area of the bonding surface (1a) and the bonding surface (21) small. Therefore, a pressure (load per unit area) applied to the bonding surfaces (1a and 21) is increased, and thus the diffusion bonding of the bonding surfaces (1a and 21) is performed by a high pressure. Similarly, a bonding surface (3a) of a lower member (3) and a bonding surface (23) of the frame member (2) are also subjected to the diffusion bonding by a high pressure. As a result, a heat transport device (100) having a high hermeticity can be manufactured without increasing an entire load (F) applied at the time of the diffusion bonding.
