Schematic view of a multi-capillary neutron lens and its focused
images
A neutron-focusing lens has been developed using 110 multi-capillary
glass fibers with a length of 140 mm and a diameter of 0.5 mm.
Each fiber contains 1,200 hollow channels with a diameter of 10
micrometer. Fig. 11-7 shows the converging images obtained along
the principal axis. Neutron convergence was clearly confirmed
at a focal point 50 mm from the exit. |
