During previous measurement campaigns at the two-beam test stand (TBTS), a (changing) transverse coupling of the beam has been observed. In recent
measurements, we did a first investigation of this phenomena and could quantify the transverse coupling with the help of quadrupole scans. Furthermore,
we observed a change of the degree of coupling depending on the RF power in the accelerating structures. A possible explanation might be the presence of (skew) quadrupole or octupole fields in the ACSs.
