The CERN West Area Neutrino Facility (WANF) [42] provides an
essentially pure 
beam.
It has been in operation for over 20 years and was largely rebuilt
in 1992-1993 [43, 44, 45] for the CHORUS and NOMAD
experiments. It has now been operating for three years with record
intensities.
We propose a limited number of modifications to its present configuration
which can be implemented using existing infrastructure and expertise, and
with minimal additional expenditure.
