The Research of High-Performance Integrator for ITER Poloidal Field Converter Measurement System

Rogowski coil is used to measure the current of the thyristor in ITER poloidal field converter, the output of the Rogowski coil is the differential of current over time, so the result should be synchronized with input signal by using the integrator. In the process of measuring, the integral drift is caused by the input offset current, input offset voltage and the input bias current, which produces errors which will be larger after a long time, so something should be taken to decrease the errors. Then a real-time way of compensation was proposed in this paper based on the foregoing analysis. According to the method, the high-performance integrator was designed and tested to fulfill the demand of decreasing the errors by simulation analysis and experimental test.     

Overview of the TFTR Computer System

The Tokamak Fusion Test Reactor (TFTR) is an experimental device built to study the physics and engineering problems of magnetically confined plasmas with temperatures and densities close to those that would exist in an actual fusion reactor. One of the prime goals of TFTR is to reach scientific breakeven, which is defined as the point where the amount of power used to maintain plasma temperatures is equal to the amount of power released through fusion reactions. The purpose of this paper is to give an overview of the computer system that provides the control, monitoring, data collection and analysis functions for TFTR.     

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. Kellogg Radiation Laboratory[l]. 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.

Computer Control System for Sodium Test Loops

A digital computer system was developed for automatic operation of the Toshiba Sodium Test Loops, intended for studying the control system of liquid metal fast breeder reactors.

The test installation is controlled by a system of two TOSBAC-40C central processing units, which take care of plant monitoring, data logging, information display, sequence control and closed loop control. The operator console linked to the computers can handle more than 3,000 process input/output signals. The state of the plant and measured data are displayed on two color cathode-ray tube installed on the console. Normal operation of the four loops constituting the installation can be supervised by one single operator.

Safety in the case of power failure and other emergencies is assured by a safety protection system that functions independently of the computer system.
