Muon detection studied by pulse-height energy analysis: Novel converter arrangements.

摘要: Muons are conventionally measured by a plastic scintillator–photomultiplier detector. from processes in ultra-dense hydrogen H(0) detected here novel type of converter front photomultiplier. The muon detection yield can be increased relative to that observed with scintillator at least factor 100, using metal, semiconductor (Ge), or glass for interaction the muons penetrating through metal housing This process is due transient formation excited nuclei well-known capture, giving beta decay. main experimental results shown form electron energy spectra directly Events which give high-energy tail probably gamma photons muons. Sharp and intense x-ray peaks muonic aluminium material observed. conversion Ge converters has time constant order many minutes reach final level, while stabilized faster. constants not lifetimes neutrons but internal charging insulating material. Interaction this high voltage photomultiplier
