Abstract

An INP‑16/350 xenon flash tube based on reinforced electrode assemblies was developed. As compared to the similar serially produced lamp INP‑16/580, the new lamp has the same dimensions but reduced discharge gap and reduced filling gas pressure. A stable quasi-arc operating mode of the lamp was reached with duration of radiation pulses of up to ten seconds when forcing power supply. The amplitude on time dependences of the lamp’s radiant exitance are formed by means of computer control of the temporal shape of the thyristor rectifier current pulses. For studying of the thermal overloads of the lamps, the methodology and IR-range optical pyrometry means were designed both, for the quartz bulb and for the electrode. The dependence of the latter’s temperature on energy deposition was studied using two custom-made radiometers. The load and radiation characteristics of the new lamp and the said analogue were compared. The new lamp is capable to operate rather reliably with high-power supply and energy deposition overload of up to 100 times in the single second-long flash mode with natural air cooling.

带有强化电极组件的氙气闪光管强制供电模式研究

开发了一种基于强化电极组件的INP‑16/350氙气闪光管。与同类系列生产的INP‑16/580灯相比，新灯具有相同的尺寸，但减少了放电间隙，降低了填充气体压力。在强制供电时，达到了稳定的准电弧工作模式，辐射脉冲持续时间可达10秒。通过计算机控制晶闸管整流电流脉冲的时间形状，形成了灯辐射出口的幅值与时间的关系。为了研究灯泡的热过载问题，设计了石英灯泡和电极的红外范围光学热测量方法和方法。利用两台定制的辐射计研究了后者的温度对能量沉积的依赖关系。比较了新灯和模拟灯的负载和辐射特性。新灯能够在高电源和能量沉积过载下相当可靠地运行，在自然空气冷却的单秒长闪光模式下可达100倍。
