The numbers were worked out for scenarios at a future Stopped Muon Source (SMS) of a neutrino factory at CERN \cite{Aysto_01}. They are based on a muon flux of $10^{21}$ particles per annum in which beam will be available for $10^7$ s. Typical beam requirements are given in Table \ref{tab:LE_beams}. \label{tab:LEexpts} % } % \end{table} % \end{center}
