The beam telescope of the RD51 collaboration at CERN consists of several triple-GEM detectors, each with an active area of 10x10 cm2, and additional scintillators to generate a trigger signal for the timing of events. The detectors are equipped with the new VMM3a ASIC coupled to the Scalable Readout System (SRS). In this configuration, the system can provide a rate capability of the order of a few MHz, spatial resolutions in the order of 50 µm and time resolutions in the nanosecond regime. During the RD51 test-beam campaigns in 2023 the system has been improved in terms of powering and noise. The telescope provided data to different groups with different detector technologies (e.g. GEM-TPC, 30×30 cm2 AMBER prototype, MPGD DHCAL). The talk will discuss the improvements of the system and present results of different detectors under test. This work has been sponsored by the Wolfgang Gentner Programme of the BMBF (grant no. 13E18CHA).
