	Funding: This work is supported by the German Federal Ministry of Education and Research (BMBF) under Contract No. 05K19RO1 and 05K22RO2. A vacuum sealed prototype of an electro-optical bunch-arrival-time monitor has been commissioned in 2023. It comprises of a pickup-structure and a low-pi-voltage ultra-wideband traveling wave electro-optical modulator. The stainless-steel body of the pickup structure is partially produced by additive manufacturing and comprises four pickups as well as an integrated combination network on a printed circuit board. This novel design aims to enable single-shot bunch-arrival-time measurements for electron beams in free-electron lasers with single-digit fs precision for low bunch charges down to 1 pC. The theoretical jitter charge product has been estimated by simulation and modeling to be in the order of 9 fs pC. The new prototype is tailored for validation experiments at the ELBE accelerator beamline. In this contribution first measurement results are presented.

	Electro-optical detection has proven to be a valuable technique to study temporal profiles of THz pulses with pulse durations down to femtoseconds. Recently, a numerical reconstruction strategy called DEOS [1] (Diversity Electro-Optical Sampling) proved to be much more efficient in retrieving ultrafast input signals. First tests at the European X-ray FEL (EuXFEL) in Hamburg show a 200 fs temporal resolution over more than 10 ps recording length. This technique, however, requires to measure both orthogonal polarizations of the sampling laser pulse simultaneously. Further adaptations to the existing design of the compact EOD bunch length monitor [2] are needed to fully implement the new measurement strategy, which will be presented in this paper. [1] E.
