Abstract :
To accept, select and process the information of colliding beam experiments we have constructed a DAQ called “KLYUKVA”. The main principles are: distribution of 500 MHz clock frequency from one center for measurements of time intervals; disposition of all registering electronics in special crates with fast databus and triggers communications; using of fast processors with built-in algorithms as crate controllers. This DAQ with triggers can provide 250 selected and processed events per second for on-line computer with ∼15% of losses. The DAQ works now on all three INP detectors: KEDR, SND and KMD-2.
