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.
The Data Acquisition and Control Systems for ATF:an Overview
A data acquisition and control system is being developed to support the Advanced Toroidal Facility (ATF) at the Oak Ridge National Laboratory (ORNL). This system has two separate elements: a VAX-based data acquisition and management system and a status and control system that uses programmable logic controllers (PLCs). Although these systems can operate independently, they are intended to cooperate fully and complement one another. This paper presents an overview of the hardware components, software architecture, and operations of these systems.
