Determining the influence of transversal beam excitation on beam size and dynamics at KARA

Significant beam dynamics parameters, such as energy
spread or transversal beam size, can be calculated from
the transversal bunch profile. At the Karlsruhe Research
Accelerator (KARA), located at the Karlsruhe Institute of
Technology (KIT), the beam size in the storage ring is be-
ing investigated using the KArlsruhe Linear arraY detector
for MHz rePetition rate SpectrOscopy (KALYPSO), a line
array that examines the synchrotron radiation emitted at a
five-degree port of a dipole magnet. Trench-Isolated Low-
Gain Avalanche Diode (TI-LGAD) technology provides su-
perior sensitivity compared to conventional silicon detectors,
thereby facilitating the study of low-charge bunches. As the
KALYPSO system can be triggered at several megahertz,
turn-by-turn analysis can be performed at KARA, which
has a revolution frequency of 2.7 MHz . In addition to the
study of the energy spread, the analysis of beam size and
position modulations can be performed. These can either
occur naturally or be induced by a white noise signal on a
strip line. In this contribution, the influence of transversal
beam excitation on beam size and time-resolved dynamics

at KARA is investigated.
