Multi-strip Multi-gap Resistive Plate Counters (1) (MMRPCs) were developed for FOPI to improve the existing ToF system and in particular to obtain charged kaon identification with the FOPI setup. In order to achieve a full phase space coverage, a time resolution of better than 100 ps is required for the complete system. The system performance was evaluated (2) with a proton test beam at the SIS using a pre-production series of the counters. The result of the performance evaluation will be reported demonstrating the capability of the counter concept. The readout of the MMRPCs is done via a custom electonic design (3) developed at GSI, using a 3-stage broad-band preamplifier and an ASIC based TAC digitizer (4). This electronic system is optimized for processing small RPC signals (85 fC on average) and has an excellent intrinsic time resolution of less than 15 ps. We will discuss the status of the series production and the integration of the MMRPCs that aims at installing the full subsystem into the FOPI setup in spring 2007. (1) E.C. Zeballos et al. Nucl.
