| Outline of Final Research Achievements |
Negative muon beams obtained by accelerators have high intensity but are difficult to converge. The focused negative muon beam enables us to obtain elemental and isotopic distributions and chemical bonding distributions on the surface of materials with nondestructive, extremely high sensitivity, 3D, with several 10 nm resolution. The challenge was to create a scanning negative muon microscope, a revolutionary analytical microscope that visualizes image of the elemental, isotopic distributions and chemical bonding distributions for the bio-materials.
Finally, we succeeded in a proof-of-principle experiments extracting ~5KV ultra-low-velocity negative muons generated by friction, and also in converging the ultra-low muons by using carbon nanotube thin films of 20 nm in thickness. Since the most important basic principle verification has been achieved that we will be able to realize our dream ultra-low-enegy negative muon scanning microscope in the future, if the budget is available.
