GAMMA - RADIOGRAPHY USING A LASER - PLASMA SOURCE

Аннотация

Gamma radiography using a laser-plasma source represents an advanced non-destructive testing technique with significant potential for industrial and medical applications. This study investigated the generation of gamma rays through laser-driven plasma interactions and their application in high-resolution radiography. A high-intensity laser pulse was focused onto a solid target, producing a relativistic plasma that emitted bremsstrahlung and characteristic gamma radiation. The emitted gamma spectrum was analyzed using spectroscopic methods, and radiography was performed on test objects to evaluate spatial resolution and contrast sensitivity. The results demonstrated that laser-plasma sources can produce sufficiently intense and collimated gamma beams for high-quality imaging, with resolutions comparable to conventional gamma sources.
