Due to the wide range of heavy ion beam intensities and energies in the
GSI linac and the associated transfer channel to the synchrotron, several
different types of emittance measurement systems have been established.
Many common devices such as slit/grid or dipole-sweep systems are
integrated into the GSI control system. Other systems like the single
shot pepper pot method using CCD-cameras or stand-alone slit/grid set-ups
are connected to personal computers. An overview is given about the
various systems and their software integration. Main interest is directed
on the software development for emittance front-end control and data
analysis such as evaluation algorithms or graphical presentation of the
results. In addition, special features for improved usability of the
software such as data export, project databases and automatic report
generation will be presented. An outlook on a unified evaluation
procedure for all different types of emittance measurement is given.

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.
