| 摘 要： | 江门中微子试验中使用的光电倍增管需要长时间承受高静水压力作用,由于光电倍增管外壳使用膨化硅玻璃制造,受自身结构微观缺陷影响不可避免的有发生碎裂的可能,并引发光电倍增管的水下内爆(Implosion),对其周围设施造成危害。在可加压密封罐中进行带有气囊的光电倍增管水下内爆试验,使用高速摄像和压力传感器记录实验过程数据。并将试验结果与无气囊条件下的光电倍增管水下内爆相关数据进行对比,探究了使用气囊进行光电倍增管水下内爆防护的可行性,为光电倍增管的水下内爆防护提供新的思路。 |

| Abstract: | The underwater implosion test of photomultiplier tube with air bag was carried out in pressurized sealed tank. The experimental process data were recorded by high-speed camera and pressure sensor. The experimental results are compared with the data of photomultiplier tube underwater implosion without balloon. The feasibility of using balloon to protect photomultiplier tube underwater implosion is explored, which provides a new idea for the protection of photomultiplier tube underwater implosion. |
| Keywords: | Photomultiplier tube implosion shock wave high-speed camera experimental study |
