摘要： A sample holder used for a sample processing apparatus that applies a charged particle beam to a sample to process the sample. The sample holder includes a holder base thermally connected to a cooling source, a rotating body rotatably supported on the holder base to hold the sample, and a drive unit that rotates the rotating body. The rotating body has a sliding surface that comes into slidable surface contact with the holder base.

摘要： There is provided a radiation detection apparatus capable of effectively discriminating between noise and X-ray signal. The radiation detection apparatus includes a detector for detecting radiation and producing a detector output signal, a first differential filter having a time constant and operative to differentiate and convert the detector output signal into a first pulsed signal, a second differential filter having a time constant greater than that of the first differential filter and operative to differentiate and convert the detector output signal into a second pulsed signal, and a noise detection section for detecting noise based on the difference in timing between peaks of the first and second pulsed signals.

摘要： 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.

摘要： A second polymer is prepared through derivatization of a first polymer. Kendrick Mass Defect (KMD) analysis is applied on a mass spectrum of the second polymer, to thereby produce a plot. Meanwhile, a plurality of mass candidates for a non-primary-chain segment are calculated based on a mass spectrum of the first polymer. The KMD analysis is applied on the plurality of mass candidates, to thereby produce reference images. A mass of the non-primary-chain segment is identified through matching of two KMD analysis results.

摘要： There is provided a sample milling apparatus capable of mitigating heat damage to a sample. The apparatus mills the sample by irradiating it with an ion beam and includes: an ion source for emitting the ion beam; and a shield plate placed on the sample and covering a part of the sample. The shield plate includes: a shield surface on which the ion beam impinges; and a bottom surface connected to the shield surface and forming a bottom edge. The bottom surface is smaller in area than the shield surface.

摘要： An NMR apparatus includes a depressurizing device for depressurizing an NMR probe, a gas supply device for supplying gas into the NMR probe to thereby pressurize the NMR probe, and a control device. The control device alternately repeats depressurization of the NMR probe, using the depressurizing device, and pressurization of the NMR probe, using the gas supply device. This replaces the gas in the NMR probe.

摘要： In an analyzer, an image processing unit performs processing of: dividing a measurement image into a plurality of partial measurement images, and dividing a reference image into a plurality of partial reference images; calculating a positional deviation amount of each of the partial measurement images relative to a corresponding partial reference image among the partial reference images; determining whether the positional deviation amount is a threshold or less; and correcting positional deviation of the measurement image based on the positional deviation amounts of the plurality of partial measurement images when the image processing unit has determined that the positional deviation amount is not the threshold or less.
