摘要

DIII-D托卡马克设施目前正在升级其电子回旋共振加热系统。新系统基于瓦里安公司开发的110 ghz回旋管。作为升级的一部分，需要对超导磁体电源进行远程控制和精确监测。110 ghz的回旋管超导磁体有8个线圈，由电流调节电源供电。设计了一个模拟-数字(A/D)系统，允许远程线圈电流监测和电源编程。A/D系统是一个8通道多路复用，16b，双向，光纤连接，A/D遥测系统。讨论了设计问题和权衡，以及系统内使用的结果

Eight channel-16 bit, bidirectional analog to digital monitoring and control system

The DIII-D tokamak facility is currently upgrading its electron cyclotron resonance heating system. The new system is based on 110-GHz gyrotrons developed by Varian. As part of this upgrade, the superconducting magnet power supplies were required to be remotely controlled and monitored accurately. The 110-GHz gyrotron superconducting magnet has eight coils, which are energized by current regulating power supplies. An analog-to-digital (A/D) system was designed to allow remote coil current monitoring and power supply programming. The A/D system is an eight channel multiplexed, 16-b, bidirectional, fiber optically linked, A/D telemetry system. Design concerns and tradeoffs are discussed, as are the results of in-system use.<>
