  • Publication number: 20190189418
    Abstract: A microchannel plate (MCP) 41 in an ion detection section 4 multiplies electrons. An anode 42 detects those electrons and produces a current signal. An amplifier 44 converts this signal into a voltage signal. A low-pass filter 5A acting as a smoothing section 5 is located at the output end of the amplifier 44. A waveform-shaping time adjuster 6 adjusts the time constant of the low-pass filter 5A beforehand according to the response time of the MCP 41, mass-to-charge ratio of an ion species to be subjected to the measurement, and duration of the spread of the ion species which depends on device-specific parameters. A plurality of peaks which sequentially appear in the detection signal corresponding to one ion species are thereby smoothed into a single broad peak. Thus, the distinguishability between signal waves and noise components is improved.

  • Publication number: 20190175126
    Abstract: Provided is a radiation imaging apparatus capable of performing precise imaging without performing pre-imaging in the absence of a subject. According to the present invention, it is possible to provide a radiation imaging apparatus capable of performing precise imaging without performing pre-imaging in the absence of a subject immediately before. That is, the apparatus of the present invention is provided with a phase grating 5 provided with a subject area and a reference area. Both areas each have a predetermined pattern that absorbs radiation, but the patterns are different from each other. In this area, an image of the phase grating 5 is observed in a moire pattern of a long period.
