GDB-110型光电倍增管是一种双曲面端窗、半透明双碱光阴极的管子,其阴极有效直径为110mm,窗材料为硼硅玻璃,光谱范围为320—650nm。这种管子具有探测效率高、 响应速度快、增益高等特点。其中部分管子还具有优良的单电子响应特性。其上升时间(典型值,下同)为2.1ns,暗噪声计数为700cps。主要性能与XP2041相当。 该管型配有平凹有机光导和金属外套,装有20脚管基,可直接与XP2041、R1250、EMI9823、RCA4522等管子互换。 GDB-110 type photomultiplier tube is a hyperboloid end window, translucent double-alkali photocathode tube, the cathode effective diameter of 110mm, the window material is borosilicate glass, the spectral range of 320-650nm. This tube has high detection efficiency, fast response, high gain characteristics. Some of these tubes also have excellent single electron response characteristics. The rise time (typical, the same below) is 2.1ns, dark noise count is 700cps. The main performance and XP2041 quite. The tube is equipped with a flat concave organic light guide and a metal jacket with a 20-foot tube base that can be interchangeable with XP2041, R1250, EMI9823, RCA4522 and other tubes.
