At free-electron lasers, today’s pump-probe experiments and seeding schemes make high demands on the electron bunch timing stability with an arrival time jitter reduction down to the femtosecond level. At FLASH and the upcom- ing European XFEL, the bunch train structures with their high bunch repetition rates allow for an accurate intra-train stabilisation. To realise longitudinal beam-based feedbacks a reliable and precise arrival time detection over a broad range of bunch charges, which can even change from 1 nC down to 20 pC within a bunch train, is essential. Benefit- ting from the experience at FLASH, the current bunch ar- rival time monitors, based on detection of RF signals from broad-band pick-ups by use of electro-optic modulators, are further developed to cope with the increased require- ments. In this paper, we present the new BAM prototype, including an adapted electro-optical front-end and the lat- est development of the read-out electronics based on the MTCA.4 platform.
