The Data Acquisition and Analysis Complex for the BNL Low Energy Accelerator Facility

The Data Acquisition and Analysis Complex is based on an SDS Sigma-7 computer with special purpose hardware. This complex will be time-shared by users at four independent accelerators. Each user may perform computations or data analysis while simultaneously collecting data and displaying results. A special feature of this complex is that the displays, programs and data are maintained on disc memories thus freeing the central processor and core memory for independent time-sharing tasks.
