    • a photomultiplier tube including a photocathode, an electron multiplier, an electron collector, and a power lead, wherein the photocathode and the electron multiplier are disposed in a sealed transparent vacuum envelope, the electron collector and the power lead are connected with an external circuit outside the vacuum envelope, the photocathode is formed on the entire inner surface of the vacuum envelope, and the electron multiplier is located on the internal center of the vacuum envelope to receive photoelectrons from the photocathode in all directions for electrons multiplication. Because the effective photocathode area is increased, the detection efficiency of unit light-receiving area is improved.
    • 包括光电阴极,电子倍增器,电子收集器和电源引线的光电倍增管,其中光电阴极和电子倍增器设置在密封的透明真空外壳中,电子收集器和电源引线与外部电路外部连接 真空外壳中,在真空外壳的整个内表面上形成光电阴极,并且电子倍增器位于真空外壳的内部中心,以从光电阴极沿着所有方向接收光电子用于电子倍增。 由于有效光电面积增加,单位受光面积的检测效率提高。
