A negative DC voltage is supplied to a flight tube from a negative voltage generator by turning on switching elements and turning off other switching elements during performance of a measurement, and a capacitor is charged by an auxiliary positive voltage generator by turning on a switching element. When an applied voltage is switched from a negative to a positive polarity, a large current is supplied to the flight tube from the capacitor by turning off the switching elements and turning on the switching element, and thus a capacitance is quickly charged to a positive potential. Thereafter, a stable positive DC voltage is applied to the flight tube from a positive voltage generator by turning off the switching element and turning on the switching element.
