| Abstract: | Muon-catalyzed fusion was investigated in thin solid deuterium films to determine the experimental feasibility of slow µ– production by detection of dd fusion protons as well as slow µ– collection utilizing a large-acceptance magnetic spectrometer. The spatial distribution of the fusion reaction in the film was extracted, and an optimum thickness for slow µ– emission was deduced. Collected 10 keV µ– were also successfully detected. However, the dd fusion yield being insufficient, we were not able to distinguish slow µ– via µCF from degraded µ–. |
