Experiments which could beneficially take advantage of the intense
future stopped muon source. 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}.
