通过将光阴极和第一倍增极之间的距离缩短到1 mm，并使用2500线/英寸的更精细的网格尺寸。在B≤1 T的强磁场下，24阳极线阵细网光电倍增管在脉冲高度分布中产生了清晰的单光子峰，渡越时间扩展（TTS）σTTS=100 ps，光电子探测效率为85%。
By shortening the distance between the photocathode and the first dynode to 1 mm and using a finer mesh size of 2500 lines/in. with 4 μ mφ, a 24 anode linear-array of fine-mesh photomultiplier tube has produced a clear single-photon peak in its pulse-height distribution under a strong magnetic field of B≤1 T , and provided σTTS=100 ps of transit time spread (TTS) and 85% of photoelectron detection efficiency.
