	For the low charge operation mode at the European XFEL, high bandwidth cone-shaped pickups were developed as a part of the Bunch Arrival-time Monitors (BAMs). The simulation showed that the signal parameters of interest, the signal slope and bandwidth are improved by more than a factor of six compared to the state of the art pickups. The pickups are installed at FLASH for verification. In this paper, time-domain measurements of the cone-shaped pickups at FLASH are presented. The pickup signal is recorded with a high bandwidth sampling oscilloscope. Two channel measurements are conducted with a single and a combined pickup signal in order to analyze the orbit and charge dependence of the pickup signal parameters. The measured time domain pickup signal wave form is compared to the CST PARTICLE STUDIO simulation.

	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.
