Abstract

Many high-data-rate experiments in elementary particle physics suffer large dead-times due to the slow speeds with which the on-line computer can read in data from each event. To eliminate this bottle-neck, we have designed, constructed, and made extensive use in a physics experiment of a 4 megabyte memory buffer which employs ordinary dynamic RAM memory chips and which accepts all of our event data generated during a beam spill at Fermilab at a rate of 14 Mbyte per second.
