Abstract
The KOTO data acquisition system (DAQ) collects detector PMT waveform signals and saves digitized events to permanent storage using frontend ADC modules, two levels of hardware triggers, and a computing farm. The KOTO DAQ system ran stably in 2013 with 24 kW beam power. To maintain high DAQ livetime with increasing beam power, we implemented lossless data compression inside the ADC modules and developed a new L3 computing farm. The upgraded KOTO DAQ system was able to maintain livetime above 80% with 42 kW beam power during the 2015 and 2016 runs. To sustain high DAQ livetime for data taking with beam power of 50 kW and above, an upgrade of our hardware trigger is proposed.
