Description
The SND detector takes data at the e+e- collider VEPP-2000 in Novosibirsk. We present here
recent upgrades of the SND DAQ system which are mainly aimed to handle the enhanced events
rate load after the collider modernization. To maintain acceptable events selection quality the electronics
throughput and computational power should be increased. These goals are achieved with the new fast (Flash ADC)
digitizing electronics and distributed data taking. The data flow for the most congested detector subsystems
is distributed and processed separately. We describe the new distributed SND DAQ software architecture,
its computational and network infrastructure.
