Description
The SPADI Alliance is a next-generation streaming data acquisition developing platform, aiming at a common and scalable streaming readout system. As a part of SPADI task force, we are developing a waveform digitizer board SAMIDARE to promote future standardization for the large-scale TPC-based experiments, such as E16, HypTPC, SPiRIT, MAIKo, and CAT-M. In this study, as a first application example of the SAMIDARE-based DAQ system, we applied the prototype board to the active-target detector CAT-M. It has been developed for systematic measurements of the isoscalar giant monopole resonance (ISGMR), which provide constraints on the isospin-dependent incompressibility term $K_\tau$, an essential component of the nuclear matter equation of state. CAT-M consists of a compact beam-tracking TPC (Mini-TPC), a large TPC for recoil particle detection, and silicon strip detectors. Tracking and particle identification are performed using waveform information, enabling reaction reconstruction in inverse kinematics experiments under high-intensity heavy-ion beam irradiation. In this presentation, we report the results of a performance test of the SAMIDARE prototype board, conducted under heavy-ion beam irradiation using the Mini-TPC.
