METHOD OF GENERATING X-RAY RADIATION DEVICE FOR REALISING SAID METHOD Russian patent published in 2012 - IPC H05G2/00 

FIELD: physics.

SUBSTANCE: invention discloses a method of generating X-ray radiation, involving exciting atoms of the outer surface of a target, in which a stream of liquid medium is formed at low pressure, having at least in the peripheral part of the stream cavitation regions (2) with collapse zones (3) for the cavitation bubbles (1); bringing collapse zones (3) of said stream into contact with the inner surface (7) of the target (6) and obtaining X-ray radiation (11) on the outer surface (9) of the target (6). The target (6) used is made from material having low coefficient of volumetric attenuation of an elastic ultrasonic wave, thickness equal to or greater than the length for converting the elastic ultrasonic wave excited by the impact wave (5) of the collapse zone (3) in the material of the target (6) into an impact wave (10) with a short front on the outer surface (9) of the target (6). A device for realising the method is disclosed.

EFFECT: obtaining narrow-band X-ray radiation, obtaining characteristic radiation of a defined substance, obtaining mixed characteristic radiation.
