    Abstract: A measurement method capable of easily measuring the directions of detector segments of a segmented detector relative to a scanning transmission electron microscope (STEM) image is provided. The measurement method is for use in an electron microscope equipped with the segmented detector having a detection surface divided into the detector segments. The measurement method is used to measure the directions of the detector segments relative to the STEM image. The method involves defocusing the STEM image to thereby cause a deviation of the STEM image and measuring the directions of the detector segments relative to the STEM image from the direction of the deviation of the STEM image (step S11).

    Abstract: The scanning charged particle beam microscope according to the present invention is characterized in that, in acquiring an image of the FOV (field of view), interspaced beam irradiation points are set, and then, a deflector is controlled so that a charged particle beam scan is performed faster when the charged particle beam irradiates a position on the sample between each of the irradiation points than when the charged particle beam irradiates a position on the sample corresponding to each of the irradiation points (a position on the sample corresponding to each pixel detecting a signal). This allows the effects from a micro-domain electrification occurring within the FOV to be mitigated or controlled.

    Abstract: One embodiment pertains to an apparatus for compressing an electron pulse. An electron source is illuminated by a pulsed laser and generates a pulse of electrons. The pulse enters a beam separator which deflects the electrons by 90 degrees into an electron mirror. The faster, higher energy electrons form the leading edge of the pulse and penetrate more deeply into the retarding field of the electron mirror than the lower energy electrons. After reflection, the lower energy electrons exit the electron mirror before the higher energy electrons and form the leading edge of the pulse. The reflected pulse reenters the separator and is deflected by 90 degrees towards the specimen. The fast, higher energy electrons catch up with the slow, low energy electrons as the electrons strike the specimen. The electrons are scattered by the specimen and used to form a two-dimensional image or diffraction pattern of the specimen.

    Abstract: Protein layers (1) repeating regularly in two dimensions comprise protein protomers (2) which each comprise at least two monomers (5), (6) genetically fused together. The monomers (5), (6) are monomers of respective oligomer assemblies (3), (4) into which the monomers are assembled to assembly of the protein layer. The first oligomer assembly (3) belongs to a dihedral point group of order O, where O equals (3), (4) or (6) and has a set of O rotational symmetry axes of order (2). The second oligomer assembly (4) has a rotational symmetry axis of order (2). Due to the symmetry of the oligomer assemblies (3), (4), the rotational symmetry axes of each second oligomer assembly (4) is aligned with one of said set of O rotational symmetry axes of a first oligomer assembly (3) with (2) protomers being arranged symmetrically therearound. Thus, an 2-fold fusion between the oligomer assemblies (3), (4) is produced and the arrangements of the rotational symmetry axes of the oligomer assemblies (3), (4) cause the protein layer to repeat regularly. The protein layer has many uses, for example to support molecular entities for biosensing, x-ray crystallography or electron microscopy.
