TI - Observations of the Quadrupolar Oscillations at GSI SIS-18
J2 - Proc. of IBIC2014
AB - An asymmetric capacitive pick-up was installed at GSI SIS-18 for determination of the turn-by-turn beam quadrupole moment. The pick-up geometry is simulated to estimate its sensitivity towards the beam dipole and quadrupole moments. Turn-by-turn quadrupole moment measurement allows to calculate the frequency of beam-size oscillations. Recent beam measurements using this pick-up show clear indications of the beam-size oscillations induced by the injection mismatch. In this contribution, we present these measurements and discuss their relevance for the direct determination of the incoherent space charge tune shift.
