摘要：A compact apparatus can form multi X-ray beams with good controllability.Electron beams (e) emitted from electron emission elements (15) of a multi electronbeam generating unit (12) receive the lens effect of a lens electrode (19). The resultantelectron beams are accelerated to the final potential level by portions of a transmission-type target portion (13) of an anode electrode (20). The multi X-ray beams (x) generatedby the transmission-type target portion (13) pass through an X-ray shielding plate (23)and X-ray extraction portions (24) in a vacuum chamber and are extracted from the X-rayextraction windows (27) of a wall portion (25) into the atmosphere.
