  • Patent number: 10050550
    Abstract: Downsizing a Cockcroft-Walton high-voltage generation device may cause discharge from the connections of respective components to potentially lack insulation reliability. A Cockcroft-Walton circuit (1) is configured to include capacitors (2a-1 to 2a-4) connected in series and capacitors (2b-1 to 2b-4) connected in series, each having end electrodes (22) at both ends, respectively. One capacitor (2a-1) is electrically connected with the other capacitor (2a-2), which is adjacent in series to the former at a connection (7a-1). The connection (7a-1) is arranged so as not to protrude outside a first space (9) between the end electrode (22) of the one capacitor (2a-1) and the end electrode (22) of the other capacitor (2a-2). Further, the anode of a diode (3a-1) and the cathode of a diode (3b-1) are electrically connected to the connection (7a-1).
