<p>X-ray generating equipment for generating X-ray by radiating electron beam on a target, comprising a vibration providing part for vibrating the target in the surface direction of the target, whereby, since an actually effective electron impact area on the target can be increased by moving the impact point of the electron beam on the target while maintaining the X-ray focal point position on the electron beam at a same position without varying the X-ray focal position, the concentric rise of the temperature of the target by the collision of electrons can be suppressed by dispersing generated heat, and thus the compact X-ray generating device with a long service life and a high operation rate can be provided.</p> |
