Abstract
CAPILLARY-BASED OPTICS (KUMAKHOV OPTICS) CONTROL X-RAY AND LOW-ENERGY NEUTRON BEAMS BY MEANS OF MULTIPLE REFLECTIONS AT LESS THAN THE CRITICAL ANGLE. OPTICS HAVE DEMONSTRATED THE CAPABILITY TO FORM CONVERGENT OR QUASI-PARALLEL BEAMS. SUCH CONTROLLED BEAMS HAVE APPLICATIONS IN MANY X-RAY AN NEUTRON MATERIAL ANALYSIS TECHNIQUES. ALTHOUGH THE CURRENT GENERATION OF KUMAKHOV OPTICS CAN PROVIDE SUBSTANTIAL BENEFIT, ASSEMBLY CONSTRAINTS LIMIT THE ACHIEVABLE TRANSMISSION EFFICIENCY, ENERGY RANGE, ALIGNMENT, AND MINIMUM FOCAL SPOT SIZE OF THE RESULTING BEAM. FOR MANY MATERIAL ANALYSIS TECHNIQUES, THESE BEAM PARAMETERS AFFECT THE SPATIAL RESOLUTION, DETECTION LIMITS, AND MEASUREMENT TIME. RESEARCHERS ARE IMPROVING X-RAY AND NEUTRON BEAM CONTROL BY DEVELOPING A NEW GENERATION OF KUMAKHOV OPTICS WHICH ARE MANUFACTURED AS A SINGLE PIECE. THE CHANNELS WHICH DEFLECT THE PHOTONS OR NEUTRONS HAVE VARIABLE DIAMETERS OVER THE LENGTH OF THE OPTIC. THE EFFORT INCLUDES MONTE CARLO SIMULATIONS OF X-RAY TRANSMISSION EFFICIENCY AND EXIT DIVERGENCE WITH SUCH STRUCTURES, AND EXPERIMENTAL MEASUREMENTS OF THE X-RAY TRANSMISSION PROPERTIES OF A FEW EARLY ONE-PIECE PROTOTYPES.
