We have developed a pipelined data acquisition (DAQ) system for μ SR experiments at the Japan-Proton Accelerator Research Complex (J-PARC). From September 2008, the J-PARC accelerator will begin the beam delivery to the muon source and the first μ SR experiment will be in operation. When fully operable, the muon beam intensity at the Muon Experiment Facility will be two to three orders of magnitude greater than that of the Muon Science Laboratory (KEK-MSL). This will force us to replace the detector and the DAQ system. The new DAQ system must fit the framework for the run automation at J-PARC. We have developed a new DAQ system for this purpose, which will be used in the first experiment and will be ready for new μ SR detectors for the full operation of the accelerator.
