Description
As a part of a K-program project in Japan, we are developing DAQ technology which can be used in the streaming readout of cosmic-ray air-shower detectors, but with ensuring it is applicable to experiments beyond cosmic-ray physics. This development is ongoing in collaboration with the SPADI Alliance in Japan, which provides a standardized, end-to-end system ranging from front-end electronics to the DAQ and analysis software. For gaseous detectors, the SPADI alliance currently offers the AGASA based analog front-end board and the AMANEQ TDC module as the front-end electronics. These were integrated to a single board, known as the STAG board (streaming readout with AGASA for gaseous detectors), to improve several aspects of the legacy system such as its size, cooling, cost, cabling, etc. Despite being very compact in size (8 cm x 11.5 cm), the STAG board supports 64 channel readout at 16 Mcps, has low power consumption, and has several additional capabilities. Therefore, the STAG board can be useful in the readout of compact gaseous detectors such as the SR-PPAC, high-channel-density drift chambers, and even detectors inside vacuums. This talk will present about the development, evaluation and the future plan of the STAG board, and the related streaming readout system.
