Outline of Final Research Achievements

Purpose of this work is to develop a new readout system of germanium detectors based on digital waveform sampling and analysis. I developed a waveform readout system and its performance was tested. I also developed a LSO pulsar system using LSO scintillators for in-beam energy calibration and FPGA circuits for data acquisition system.
These outcomes of this work are applied for germanium detector arrays (Hyperball-J and Hyperball-X) in J-PARC experiments.
