    Abstract: Provided are an electron gun, an electron gun component, an electron beam applicator, and an alignment method that can align the emission axis of an electron beam with the optical axis of the electron optical system of the counterpart device even when misalignment of a mounted position of the electron gun being mounted to the counterpart device is larger. The electron gun includes: a light source; a vacuum chamber; a photocathode that emits an electron beam in response to receiving light from the light source; an electrode kit; and an electrode kit drive device, the electrode kit includes a photocathode supporting part, and an anode arranged spaced apart from the photocathode supporting part, the photocathode is placed on the photocathode supporting part, and the electrode kit drive device moves the electrode kit in an X-Y plane, where one direction is defined as an X direction, a direction orthogonal to the X direction is defined as a Y direction, and a plane including the X direction and the Y direction is defined as the X-Y plane.

    Abstract: A charged particle beam device is provided that performs proper beam adjustment while suppressing a decrease in MAM time, with a simple configuration without adding a lens, a sensor, or the like. The charged particle beam device includes: an optical element which adjusts a charged particle beam emitted from a charged particle source; an adjustment element which adjusts an incidence condition of the charged particle beam with respect to the optical element; and a control device which controls the adjustment element, wherein the control device determines a difference between a first feature amount indicating a state of the optical element based on the condition setting of the optical element, and a second feature amount indicating a state where the optical element reaches based on the condition setting and executes adjustment by the adjustment element when the difference is greater than or equal to a predetermined value.

    Abstract: A method for evaluating a specimen, the method can include positioning an energy dispersive X-ray (EDX) detector at a first position; scanning a flat surface of the specimen by a charged particle beam that exits from a charged particle beam optics tip and propagates through an aperture of an EDX detector tip; detecting, by the EDX detector, x-ray photons emitted from the flat surface as a result of the scanning of the flat surface with the charged particle beam; after a completion of the scanning of the flat surface, positioning the EDX detector at a second position in which a distance between the EDX detector tip and a plane of the flat surface exceeds a distance between the plane of the flat surface and the charged particle beam optics tip; and wherein a projection of the EDX detector on the plane of the flat surface virtually falls on the flat surface when the EDX detector is positioned at the first position and when the EDX detector is positioned at the second position.
