Abstract

Beam excited signals available at the HOM coupler ports of superconducting accelerating cavities cover a wide frequency range and carry information about (amongst others) the transverse beam position. Downmixing these signals using detector diodes is a mean to measure the time dependence of the power leaving the HOM coupler with standard and non-specific oscilloscope technology. Experiments undertaken at the accelerator modules ACC1 and ACC39 at FLASH demonstrated the possibility to extract beam position data out of lowfrequency signals sampled with such a setup. These experiments as part of an ongoing study are described together with mathematical details of the evaluation scheme.
