A large array of MicroVAX computers will be used for high-speed data acquisition and online filtering in the D0 experiment at Fermi National Laboratory. We describe this system, as well as several smaller data acquisition systems now operational, with particular emphasis on the control and communication software. The computers in this array will run under(More)
The new generation of colliding beam experiments require new and more powerful systems for data acquisition. The DO experiment at Fermilab's Tevatron-I employs a multi-level trigger system to reduce the primary interaction rate of 50 KHz. to an event recording rate of 1-2 Hz. We describe the DO acquisition system, focusing primarily on the second level,(More)
