Currently proposals are under revision at CERN for future measurements with muon and hadron beams at the M2 beam line of the CERN SPS. For this experiments it is planned to transform the current classical triggered DAQ approach to a free running DAQ scheme which is based on an trigger-less read-out of all detectors, and later online and offline data reduction stages based on FPGA and x86 filter technologies (High Level Triggers). One of the first experiments is the measurement of the proton radius by elastic muon proton scattering. For this experiment two data taking phases are foreseen. For the first phase, with an low intensity muon beam a full, not reduced data sample will be written to disk. This allows a complete un-biased data analysis and the validation of an filter scheme which needed for a possible later high intensity data taking period to reduce the amount of data. The DAQ and Trigger/Filtering scheme and requirements for both of these measurements will be presented.
