A VAX Based Data Acquisition Computer System at the Nuclear Structure Research Laboratory

The Nuclear Structure Research Laboratory at the University of Rochester is developing a VAX-11/750 computer system for use in a data acquisition and analysis system. The system consists of the VAX which is networked to two LSI-11/23's which are in turn connected to CAMAC branch drivers. The CAMAC branch drivers operate both parallel and 5 MHz byte-serial highways. The network is a high speed DMA interface and is identical to the system implemented at the W.K.

The data acquisition system has been designed to allow the user to select standard program modules as building blocks to construct a system to suit the particular needs of the experiment. The division of the realtime analysis between the VAX and the LSI-11s is flexible. The LSI-11s are equipped with small array processors tlo permit high speed analysis on the satellite processors.

The central network computer is a VAX 11/750 with Unibus and Q-bus adaptors. Processing is distributed between the LSI-11s and the VAX as required to meet input-output and event processing speeds needed by the experiment. Use of the Q-bus on all machines allows CAMAC controllers and tape drives to be moved as needed between the LSI-11s and the VAX.

Multiple-User Data Acquisition and Analysis System

The nuclear physics program at the Brookhaven National Laboratory High Flux Beam Reactor (HFBR) employs a pair of PDP-11 computers for the dual functions of data acquisition and analysis. The data acquisition is accomplished through CAMAC and features a microprogrammed branch driver to accommodate various experimental inputs. The acquisition computer performs the functions of multi-channel analyzers, multiscaling and time-sequenced multichannel analyzers and gamma-ray coincidence analyzers. The data analysis computer is available for rapid processing of data tapes written by the acquisition computer. The ability to accommodate many users is facilitated by separating the data acquisition and analysis functions, and allowing each user to tailor the analysis to the specific requirements of his own experiment. The system is to be upgraded soon by the introduction of a dual port disk to allow a data base to be available to each computer.
