DAQ SYSTEM FOR SMALL-MIDDLE SIZE NUCLEAR PHYSICS EXPERIMENTS: PRESENT AND FUTURE

We are starting to develop a next generation DAQ system which consists of autonomous data taking modules distributed over DAQ network. The each module is tightly connected to its partner detector and has memorizing capability of the detector’s characteristic. The framework of present DAQ systems for nuclear physics experiments which stands on modular structure is not changed for 30 years, because it is universal and flexible. Advanced research works require more precise measurement and more detector channels, which caused difficulty of complicated cabling, increasing noise etc. The biggest difficulty is time consumed calibration work which is mandatory on each experiment and makes the analysis period so long. On the other hand, IT (Information Technology) field is growing so quickly and we can take fast CPU, big memory, network technology etc. with so small expense. It is no wonder to imagine autonomous data taking modules distributed over DAQ network as more universal and flexible DAQ system.
