    • The invention relates to an apparatus for a crater-style sampling capacitor. The apparatus includes a dielectric having a smooth crater shaped input electrode on a first surface and output and guard electrodes on a second surface. A sampling capacitor is defined by the input and output electrodes, and a guard capacitor is defined by the input and guard electrodes. The edge of input electrode is positioned below the first surface to increase surface flash over voltage, further, the input electrode is curved to eliminate corona discharge at edges of the input electrode and to reduce self-heating to negligible levels. The apparatus is suitable for high-voltage radio-frequency applications, such as a mass spectrometer, or other high-voltage applications that require an accurate sampling capacitor for amplitude control and accurate sampling of radio-frequency waveforms.
    • 本发明涉及一种用于火山口式采样电容器的装置。 该装置包括在第一表面上具有平滑的凹坑形输入电极的电介质,并在第二表面上输出和保护电极。 采样电容器由输入和输出电极定义,保护电容由输入和保护电极限定。 输入电极的边缘位于第一表面下方以增加表面闪光过电压,此外,输入电极是弯曲的,以消除输入电极边缘处的电晕放电,并将自加热降低到可忽略的水平。 该装置适用于需要精确采样电容器进行幅度控制和射频波形精确采样的高压射频应用,如质谱仪或其他高压应用。
