主要介绍了HL-2A装置上的红外摄影系统。该诊断系统主要由非制冷microbolometer焦平面探测器的红外热像仪、硒化锌窗口、火线光纤转发器、50m长光纤、磁屏蔽盒以及数据采集系统组成,可以实现高分辨、远距离的实时采集,并具有较好的抗电磁干扰能力。根据该系统所测靶板的表面温度以及靶板材料的参数,利用热传导模型可以推算出沉积在靶板上的功率密度,从而进行相关的偏滤器物理实验研究。文中也介绍了在HL-2A装置上的一些初步研究结果。
Mainly introduced the HL-2A device on the infrared photography system. The diagnostic system is mainly composed of an uncooled microbolometer focal plane detector, thermal imaging camera, zinc selenide window, firewire fiber transponder, 50m optical fiber, magnetic shielding box and data acquisition system, enabling high-resolution, long-range real-time Acquisition, and has good anti-electromagnetic interference ability. According to the surface temperature of the target measured by the system and the parameters of the target material, the thermal conductivity model can be used to calculate the power density deposited on the target so as to conduct the relevant physical study of the divertor. The article also introduced some preliminary results on the HL-2A device.
