In order to satisfy the stringent emittance
requirements of LHC, betatron matching monitors,
based on multiturn beam profile measurements, have
been proposed for the SPS and LHC. A test monitor
has been installed for evaluation in the CERN SPS first
in 1996 and improved in 1997. It is based on an OTR
screen and a fast beam profile acquisition system. It
has been used with proton beams to assess the quality
of the betatron matching from the PS to the SPS in
1998. Experience and results are presented.

For the characterisation of the ion beam delivered by
the new High Current LINAC at GSI, the time structure
of bunches and the knowledge concerning their intensity
distribution in longitudinal phase space is of great
importance. At least 100ps time resolution and the
capability of measuring long tails in the distribution were
design parameters. Taking advantage of Rutherford-scattering
to reduce the count rate, a direct time of flight
measurement technique using diamond detectors can be
applied. First results are reported. Plans for determine the
energy of individual ions by detecting secondary
electrons emitted from a thin C foil using 1m drift are
discussed.
