摘要

一个3mw(可升级到4mw) 4.6 GHz低混合电流驱动(LHCD)系统正在Alcator C-Mod上实施，以控制和维持电流剖面的演变。LHCD低功率微波和主动控制系统，使用快速矢量调制器，将为12个4.6 GHz, 250 kW速调管中的每一个提供相位和幅度控制驱动器。每个速调管的相位和功率输出将由I-Q探测器监测，并可用于等离子体射击期间速调管相位和幅度的闭环控制。同步数字控制器将用于每个控制回路，操作将与LHCD发射机和耦合器保护系统中提供的外部快速保护电路协调。

The Alcator C-Mod lower hybrid current drive experiment low power microwave and active control system

A 3 MW (upgradeable to 4 MW) 4.6 GHz Lower Hybrid Current Drive (LHCD) system is being implemented on Alcator C-Mod to control and sustain current profile evolution. The LHCD low-power microwave and active control system, using fast vector modulators, will provide a phase and amplitude controlled driver for each of twelve 4.6 GHz, 250 kW klystrons. Resulting phase and power outputs of each klystron will be monitored by I-Q detectors and made available for closed-loop control of the klystron phase and amplitude during plasma shots. Synchronized digital controllers will be implemented for each control loop and operation will be coordinated with external fast protection circuitry provided in the LHCD transmitter and coupler protection systems.

期刊介绍： 19th-Century Music covers all aspects of Western art music between the mid-eighteenth and mid-twentieth centuries. We welcome--in no particular order--considerations of composers and compositions, styles, performance, historical watersheds, cultural formations, critical methods, musical institutions, ideas, and topics not named on this list. Our aim is to publish contributions to ongoing conversations at the leading edge of musical and multidisciplinary scholarship.
