Data processing system with a micro-computer for high magnetic field tokamak, TRIAM-1

Journal Article:

Abstract

A data processing system was designed and constructed for the purpose of analyzing the data of the high magnetic field tokamak TRIAM-1. The system consists of a 10-channel A-D converter, a 20 K byte memory (RAM), an address bus control circuit, a data bus control circuit, a timing pulse and control signal generator, a D-A converter, a micro-computer, and a power source. The memory can be used as a CPU memory except at the time of sampling and data output. The out-put devices of the system are an X-Y recorder and an oscilloscope. The computer is composed of a CPU, a memory and an I/O part. The memory size can be extended. A cassette tape recorder is provided to keep the programs of the computer. An interface circuit between the computer and the tape recorder was designed and constructed. An electric discharge printer as an I/O device can be connected. From TRIAM-1, the signals of magnetic probes, plasma current, vertical field coil current, and one-turn loop voltage are fed into the processing system. The plasma displacement calculated from these signals is shown by one of I/O devices. The results of test run showed good performance.
