Advancing beta-decay experiments at RIBF (RIKEN Nishina Center) requires a robust and efficient data acquisition (DAQ) system capable of handling high-rate conditions while capturing rare decay events with minimum deadtime. This presentation introduces the development and implementation of a digital DAQ system based on fast digitizers and a customized version of the RCDAQ framework [1].
The DAQ system processes, reads out, and monitors online a large number of detector inputs in parallel. These include a wide variety of detectors: BigRIPS beamline detectors, the silicon detector array WAS3ABi, the segmented plastic detector GARi [2], neutron and gamma-ray detector arrays, and the MCP-silicon active stopper of the ZDMRTOF setup [3]. Its deployment has been pivotal in several beta-decay experiments conducted at RIKEN RIBF [4, 5, 6].
In this talk, I will present the system’s architecture, emphasizing its scalability, data-handling capabilities, and the seamless integration of diverse detector types. I will also highlight experimental results that demonstrate the successful implementation of the DAQ system for the active stopper WAS3ABi, GARi and MCP-Si.
