Former measurements of extracted ion beams from the
GSI heavy ion synchrotron SIS showed large current fluctuations
in the microsecond region with a high peak-to-average
ratio. To adapt our Cryogenic Current Comparator
(CCC) to this time structure the detector’s electronics have
been carefully modified.
The most important improvement of the new DC
SQUID system affects the enlargement of the bandwidth
and the slew rate of the measuring system. In addition the
existing data acquisition system for e.g. SEMs (Secondary
Emission Monitors) was extended to digitize the CCC signals
simultaneously. Measurements of Argon beams will
be shown to demonstrate the improved capabilities of the
upgraded Cryogenic Current Comparator.

The complex mathematical algorithms and procedures
to extract emittance data from intensity distributions
measured with a single shot pepper-pot device are
described. First results of mathematical evaluation from
the commissioning of the new GSI pre-stripper linac
structures are presented.
