摘要： In order to reduce an influence of disturbance propagation noise inside and outside a signal detection device and improve signal detection accuracy, the present disclosure provides a signal detection device including: detection equipment including a photoelectric conversion element configured to convert a photon as a detection target into a current signal, and a current-voltage converter configured to convert the current signal into a voltage signal; a transmission unit configured to transmit the voltage signal; and a data collection unit configured to detect and collect the transmitted voltage signal. Here, the detection equipment is disposed inside a first shield case connected to a frame ground. The current-voltage converter includes a differential amplifier having first and second input terminals, the first input terminal is connected to a first output terminal of the photoelectric conversion element via a first input resistor, the second input terminal is connected to a second output terminal of the photoelectric conversion element and a ground via a second input resistor having a resistance value larger than that of the first input resistor. First and second output terminals of the current-voltage converter are connected to the data collection unit by a cable transmission unit. The cable transmission unit is connected to the ground together with the current-voltage converter and the data collection unit (see FIG. 1).

摘要： The mass spectrometer includes a sample stage, an irradiation unit that irradiates the sample with an energy beam and ionizes a component of the sample while maintaining positional information of the sample in a region irradiated with the energy beam, an extraction electrode that extracts the ionized sample from the surface of the sample by a potential difference from the sample stage, an MCP that emits electrons in accordance with the ionized sample, an imaging part that acquires an image based on the electrons emitted by the MCP, and a control unit that controls operations of the irradiation unit, the extraction electrode, and the imaging part. The control unit changes the potential of the extraction electrode at a timing in accordance with the detection target component after the irradiation of the energy beam by the irradiation unit, and causes the imaging part to acquire an image as an analysis target in a period in accordance with the detection target component.
