A KUMAKHOV LENS WITH A ROTATING ANODE TO OBTAIN AN X-RAY SOURCE, AS AN ADVANTAGEOUS ALTERNATIVE TO SYNCHROTRONS

MEASUREMENTS AND CALCULATIONS MADE IN THE SOVIET UNION INDICATE THE POSSIBILITY OF USING A NEW CAPILLARY-BASED X-RAY OPTICAL SYSTEM TO INCREASE THE INTENSITY AND DECREASE THE DIVERGENCE OF LABORATORY X-RAY SOURCES SUFFICIENTLY FOR THEM TO COMPETE WITH, AND IN SOME CASES EVEN SURPASS, SYNCHROTRON SOURCES FOR SOME APPLICATIONS. THIS PHASE I PROJECT IS INVESTIGATING THE FEASIBILITY OF SUCH SYSTEMS BASED ON CRITICAL CALCULATIONS OF THE PROPERTIES OF SINGLE CAPILLARY AND POLYCAPILLARY FIBERS, MEASUREMENT OF RELEVANT TRANSMISSION PROPERTIES AND DIVERGENCES FOR SINGLE AND POLYCAPILLARY FIBERS AND FIBER BUNDLES, AND MODELING OF THE PROPERTIES OF COMPLETED LENS STRUCTURES. THE INTENSITY AND RESOLUTION AFTER TRANSMISSION THROUGH A BRAGG MONOCHROMETER ARE ALSO BEING INVESTIGATED.
