abstract = {The quality of slowly, typically several seconds, extracted
beams from the GSI synchrotron SIS18 is characterized with
respect to the temporal beam stability, the so-called
spillμstructure on the 100 µs scale. A pilot experiment
was performed utilizing transverse emittance exchange to
reduce the beam size in the extraction plane, and the
improvement of spillμstructure was found. Important beam
instrumentation comprises an Ionization Profile Monitor for
beam profile measurement inside the synchrotron and a
plastic scintillator at the external transfer line for ion
counting with up to several 10⁶ particles per second and
20 µs time slices. The performant data acquisition systems,
including a scaler and a fast Time-to-Digital Converter
(TDC), allow for determining the spill quality. The
application of the TDC in the measurement and related MAD-X
simulations are discussed.},
