摘要: 通过在相衬成像系统光路中引入电控安全快门控制激光输出,并使用延迟电路实现了安全快门与HL-2A放电运行的同步触发,保障了诊断系统的安全运行,安全快门时间响应为26ms,其抖动误差1ms;利用四象限传感器实现了激光束斑位置的实时监测,获得了HL-2A装置垂直和水平方向的振动数据。所发展的电控快门技术和激光实时监测系统不仅能够大幅提高相衬成像系统的安全性和可靠性,对于HL-2A/2M装置诊断系统的发展和完善也具有重要意义。

Abstract: An electronically controlled safety shutter is introduced into the optical path of the phase contrast imaging system to control the laser output, and a delay circuit is used to achieve the synchronous triggering of the safety shutter and HL-2A discharge to ensure the safe operation of the diagnostic system. The temporal response of the safety shutter is 26ms with an error of 1ms. The four-quadrant sensor is used to realize the real-time monitoring of the laser beam spot position, and obtain the vertical and horizontal vibration data of the HL-2A tokamak. The electronically controlled shutter technology and laser real-time monitoring system developed in this research can not only raise greatly the safety and reliability of the phase contrast imaging system, but are of great significance to the development and optimization of the diagnostic systems on HL-2A and HL-3 tokamak.
