Performance of the new RD51 VMM3a/SRS beam telescope — studying MPGDs simultaneously in energy, space and time at high rates

The RD51 collaboration maintains a common infrastructure at CERN for its R & D activities, including two beam telescopes test campaigns. Recently, one of the has been equipped and commissioned with new multi-channel charge-sensitive front-end electronics based on ATLAS/BNL VMM3a ASIC Scalable Readout System (SRS). This allows to read out detectors high rates (up MHz regime) time resolutions order 1 ns ability handle different detector types sizes, due larger dynamic range compared previous APV25 ASIC. Having studied improved telescope's performance over course three campaigns, results are presented in this paper.
