Abstract

By heating a high-temperature bath with a heater, atomic gas is generated in the high-temperature bath from an atomic source. A magneto-optical trap is realized by a laser beam reflected by a right-angled conical mirror and a magnetic field formed by a magnetic field generator, and the atomic gas is confined by using the magneto-optical trap and cooled. The cooled atoms are output from an opening to the outside of a slow atom beam generator by a laser beam, which is a push laser beam. A slow atomic beam is thereby formed.

Abstract

An electron beam accelerated using a first acceleration voltage is applied to respective positions on a sample to obtain spectra A at the respective positions, and an electron beam accelerated using a second acceleration voltage different from the first acceleration voltage is applied to the respective positions on the sample to obtain spectra B at the respective positions. Then, a spectral ratio A/B of the spectra is calculated at each of the positions to generate a waveform representing the spectral ratio A/B. The value of a spectral ratio A/B in an energy region of interest is extracted from each of the waveforms. The extracted values are mapped onto points corresponding to the respective positions on the sample, whereby a spectral map is generated. The spectral map is displayed.

Abstract

A composition estimation target peak is selected from a mass spectrum of a sample, and a group of measured isotope peaks related to the composition estimation target peak is selected. A composition candidate for the sample is estimated based on the composition estimation target peak. A distribution of a theoretical isotope peak corresponding to the composition candidate is calculated. Presence or absence of an adduct ion or a desorbed ion in the sample is determined based on a first mass difference between isotopes in a distribution of the measured isotope peaks and a second mass difference between isotopes in the distribution of the theoretical isotope peak.

A sample milling apparatus includes an ion source, a swinging mechanism for swinging a sample, a positioning camera for bringing a target milling position on the sample into coincidence with the impact point of an ion beam, and a display section for displaying an image captured by the positioning camera. The adjustment method starts with observing the trace of the impinging ion beam left on the sample with the positioning camera while the position of the positioning camera is held relative to the swing axis of the swinging mechanism and capturing an observation image. Then, a display image to be displayed on the display section is extracted from the observation image based on the position of the trace, thus bringing the beam impact point and the position of the field of view of the display image into coincidence.

Abstract

A charged particle beam apparatus includes: a specimen chamber; a specimen holder that is disposed in the specimen chamber; a specimen exchange chamber that is connected to the specimen chamber; a transporting mechanism that transports a specimen between the specimen chamber and the specimen exchange chamber; a first temperature sensor that measures a temperature of the specimen holder; a second temperature sensor that measures a temperature of the transporting mechanism; and a control unit. The control unit: calculates a temperature difference between the specimen holder and the transporting mechanism based on the temperature of the specimen holder and the temperature of the transporting mechanism when the control unit has received an instruction to transport a specimen; determining whether the temperature difference is a threshold or more; and stopping transportation of a specimen when the control unit has determined that the temperature difference is the threshold or more.

Abstract

A mask member is provided at an entrance opening of a mirror unit. Of a first diffraction grating and a second diffraction grating, when the second diffraction grating is used, the mask member masks preceding mirrors. With this process, aberration caused by reflective X-ray is suppressed. When the first diffraction grating is used, the mask member does not function. Alternatively, the mask member and another mask member may be selectively used.
