Two different systems are currently under development at GSI's heavy ion
facility to measure transverse beam profiles using optical emitters. At
the GSI-LINAC for energies up to 15 MeV/u residual gas fluorescence is
investigated for pulsed high current beams. The fluorescence of N2 is
monitored by an image intensified CCD camera. For all ion species with
energies above 50 MeV/u slowly extracted from the synchrotron SIS a
classical viewing screen system is used. Three different target materials
have been investigated and their behavior concerning efficiency,
saturation and timing performance is evaluated. Both systems (will) use
CCD cameras with a digital read out using the IEEE 1394 standard.

For the sensitive process of slow extraction from a synchrotron
a reliable control of the beam losses is needed.
We have tested several types of particle detectors mounted
at the extraction path of the SIS: A BF-tube for pure neutron
detection, a liquid and a plastic scintillator detecting
neutrons, gammas and charged particles and an Argon filled
ionization chamber mainly sensitive to charged particles.
While the count rate is quite different, the time evolution of
all detector signals during the spill are similar, but the plastic
scintillator has the highest dynamic range. This type is
going to be used for beam alignment.
