  The Fermilab Linac delivers a variable intensity, 400-MeV beam to the The
MuCool Test Area experimental hall via a beam line specifically designed to
facilitate measurements of the Linac beam emittance and properties. A 10 m,
dispersion-free and magnet-free straight utilizes an upstream quadrupole
focusing triplet in combination with the necessary in-straight beam diagnostics
to fully characterize the transverse beam properties. Since the Linac does not
produce a strictly elliptical phase space, tomography must be performed on the
profile data to retrieve the actual particle distribution in phase space. This
is achieved by rotating the phase space distribution using different waist
focusing conditions of the upstream triplet and performing a de-convolution of
the profile data. Preliminary measurements using this diagnostic section are
reported here.
