Abstract
In the present invention, a ferroelectric body is irradiated with ultraviolet light, and the ferroelectric body is caused to stably generate electric potential. A method for radiating charged particles, in which the UV-light-receiving surface of the ferroelectric body that receives UV light and is caused to generate a potential difference is irradiated with UV light having a wavelength not transmitted by the ferroelectric body, and charged particles are radiated from the charged-particle-radiation surface of the ferroelectric body, wherein the UV-light-receiving surface is irradiated with pulses of UV light at a peak power of 1 MW or greater. The pulse width of the UV light is measured in picoseconds (less than 1×10−9 seconds), and the UV pulses can be transmitted by fiber.
