An X-ray analyzer includes: an X-ray detector that detects an X-ray emitted from a specimen and outputs a signal having a step that has a height corresponding to energy of the X-ray; a pulse generation circuit that converts the signal output from the X-ray detector into a first pulse signal; a pulse-width setting circuit that sets a pulse width; a pulse-width conversion circuit that converts a pulse width of the first pulse signal into the pulse width set by the pulse-width setting circuit to form a second pulse signal; a pulse-height discriminator that discriminates the second pulse signal according to a pulse height of the second pulse signal; a counting circuit that calculates a counting rate of the discriminated second pulse signal; and a counting-loss correction processing unit that corrects the counting rate. The counting-loss correction processing unit corrects the counting rate based on the pulse width.

Provided is a tip capable of repeatedly regenerating a single-atom termination structure in which a distal end is formed of only one atom. A tip (1) having a single-atom termination structure includes: a thin line member (2) made of a first metal material; a protruding portion (4) made of a second metal material, which is formed at least in a distal end portion (2a) of the thin line member (2), and has a distal end terminated with only one atom; and a supply portion (5) made of the second metal material to be supplied to the protruding portion (4), which is formed in the vicinity of the distal end portion (2a) of the thin line member (2).

The present disclosure relates to integrating microdevices into a system substrate. In particular it relates to measuring microdevices using an electron beam method using one or several tips as Ebeam sources. The disclosure further outlines methods to target Ebeams effectively to produce an optimum result with minimal damage to adjacent microdevices and components.

An electron microscope includes: a display control unit which sequentially acquires electron microscope images of a sample and causes a display unit to display the electron microscope images as a live image; an analysis area setting unit which sets an analysis area on the sample based on a designated position on the live image designated by pointing means; and an analysis control unit which performs control for executing elemental analysis of the set analysis area. The analysis area setting unit sets, as the analysis area, an area on the sample which corresponds to a continuous area including the designated position and having brightness comparable to brightness of the designated position.

The radiation analyzing apparatus irradiates an object including a plurality of elements with a first radiation, detects a plurality of rays of a second radiation emitted from the object irradiated with the first radiation, derives an energy spectrum based on a signal of each of the plurality of rays of the second radiation, detects detection energy, which is energy absorbed in a reference element that is an element used as a reference or is energy emitted from the reference element, based on the energy spectrum, and corrects the energy spectrum based on reference energy information, which is previously stored in a storage unit and indicates reference energy that is energy absorbed in the reference element or is energy emitted from the reference element, and the detection energy.

Provided is a compact device which captures, over a large solid angle range, electrically charged particles emitted from a point source and parallelizes the trajectories of said charged particles. The present invention is configured from: an electrostatic lens comprising a plurality of axisymmetric electrodes (10-14) and an axisymmetric aspherical mesh (2) which has a surface that is concave away from the point source; and a flat collimator plate (3) positioned coaxially with the electrostatic lens. The acceptance angle for the electrically charged particles generated from a point source (7) is 30 or greater. The shape of the aspherical mesh (2), and the potentials and the positions of a ground electrode (10) and application electrodes (11-15) are adjusted so that the trajectories of the electrically charged particles are substantially parallelized by the electrostatic lens. The electrostatic lens and the flat collimator plate are positioned on a common axis.
