METHOD AND APPARATUS FOR GENERATING PULSED GAMMA-RADIATION OF SHORT-LIVED ISOMERS OF ATOMIC NUCLEI |
摘要 |
FIELD: physics, optics.SUBSTANCE: invention relates to laser engineering and techniques of forming charged particle beams and generating electromagnetic radiation flux. A source optical pulse of a high-power femtosecond laser radiation source is focused in a vacuum chamber by a focusing system onto a gaseous converting target, for example in the form of a gas jet. The required laser pulse intensity for efficient generation of an electron stream is achieved by varying parameters of the high-power femtosecond laser radiation source and the focusing system. The electron stream from the converting target passes through a condensing selector, wherein the stream of electrons with energy sufficient to excite nuclear states is selected and focused on a target containing nuclei of the excited isotope. Further, radiation generated during decay of the excited nuclear states is transmitted to a detector.EFFECT: invention can be used particularly in designing and producing sources of pulsed (coherent) electromagnetic ionising radiation in the gamma- and X-ray ranges.5 cl |
