A new scheme of negative muon beam generation with MuCF

A new scheme of low energy negative muon source with the muon catalyzed fusion (MuCF) is described. In the MuCF reaction process, muonic helium ions ($\mu$He${}^{+}$) are created. By re-accelerating and stripping $\mu$He${}^{+}$ ions, a low emittance negative muon beam is generated.
