The data acquisition and control system for Thomson scattering on ATF - Nuclear Science, IEEE Transactions on
The two-dimensional Thomson scattering system measuring electron temperatures and densities in the Advanced Toroidal Facility ( A m is interfaced to a VAX8700 computer system running in a clustered configuration. Calibration, alignment, and operation of this diagnostic are under computer control. Extensive CAMAC instrumentation is used for timing control, data acquisition, and laser alignment. This paper discusses the computer hardware and software, system operations, and data storage and retrieval.
SAMS - the synchronization and monitoring system for ATF data acquisition
SAMS performs much of the synchronization of the distributed data acquisition system for the Advanced Toroidal Facility (ATF). SAMS is responsible for propagating shot information and managing the data system directories and logical names. This paper describes how SAMS communicates with other processes, both within the VAX cluster that supports most of the ATF data acquisition and on VAXes that are connected to the cluster via DECnet.
Intelligent memories in VLSI
A concept of an intelligent memory, called an adaptive associative system (AAS), is described from the system level down to the device level. The performance of an AAS is discussed by means of computer simulations in regard to text processing and pattern recognition, especially such outstanding features as fault tolerance, semantic association, autosegmentation, and self-organization of information. The system concept of such a memory is rendered adequate for the VLSI technique by partitioning into repetitive memory units and by introducing a nonvolatile memory cell. The importance of interaction in realizing an AAS as a microelectronic component is pointed out for both system design and VLSI technology.
