On-line data-acquisition computer systems are made in a wide range of types and sizes. In all cases at least one electronic computer is involved--a stored-program machine--because wired-program devices such as pulse-height analyzers are not considered to be computers. The rest...
The ultimate justification for assembling and using on-line data-acquisition systems must be made in terms of research output. The same considerations underlying judgments on th...
8. c. A large shared-time system of the smallest configuration whichmakes much sense consists of a large computer with a 16k memory, two typewriters, a fast punched-tape reader, four DEC tapes (or the equivalent), one IBM-compatible magnetic tap...
4. c. Process-control operations, in which the computer directs orregulates a sequence of events in an experiment. Under program control the computer monitors the course of the experiment and supplies signals that cause automatic changes in ex...
12. Chapter 3In this chapter we present a review and an analysis of total expenditures for on-line computing in a large number of laboratories supported by the Atomic Energy Commission and t...

14. Chapter 3 gives a similar review, but in this case the high-energyfield is excluded; the emphasis is concentrated on the economic aspects of data-acquisition systems used in low-and medium-energy physics. In the earlier paper, only AEC-sponsor...
7. Chapter 2The movement toward computer systems began in earnest about 1962. Much of the early work depended on the use of magnetic tape for storage of data, either raw or partially digest...

9. c. A reasonable amount of preventive maintenance is done, mostlyd. One person serves as operator and programmer (for simple jobs). He also transports magnetic tapes to the computing center for off-line data processing and performs smaller ta...
6. d. Conversational Fortran-type programs provided by someg. Complete specifications and documentation for the programming system should be supplied, so that programs prepared by users can be made compatible. It may be objected that th...
