Embodiment Construction
[0016] Such as figure 1 Shown. A high-temperature solar-blind ultraviolet phototube, including a core column 3, the top of the core column is covered with a molybdenum group transparent purple glass shell 2 which is sealed and integrated with the core column 3, and two pairs of metal straight rods 4 are installed on the core column 3 In the middle, one end of the metal straight rod 4 extends into the molybdenum group transparent glass bulb 2, and the other end penetrates from the bottom of the core column 3. Two molybdenum electrodes 1 are also provided in the molybdenum group transparent glass bulb 2, respectively. The molybdenum electrode 1 is bent into a broken oblong shape. The broken ends of the molybdenum electrode 1 are respectively bent downwards into pins that are inclined relative to the oblong surface. The pins of a molybdenum electrode are connected to a pair of metal straight rods one by one, and the two molybdenum electrodes The long round surfaces of the electrod...

The invention discloses a high-temperature solar blind ultraviolet photoelectric tube and a manufacturing method thereof. The photoelectric tube comprises a core column, a molybdenum group purple glass permeable shell, a metal straight rod and a molybdenum electrode, wherein the molybdenum group purple glass permeable shell is encapsulated on the core column; the metal straight rod is arranged inthe core column; and the molybdenum electrode is connected to the metal straight rod. When the high-temperature solar blind ultraviolet photoelectric tube exhausts air, the molybdenum group purple glass permeable shell is baked at high temperature for a long time and the molybdenum electrode is treated by an electron bombardment method. The photoelectric tube has the advantages of high sensitivity, high reliability, long service life, high response speed, high temperature resistance, no response to visible light and infrared light, light weight and the like.
Description
Technical field [0001] The invention relates to the field of photoelectric tubes, in particular to a solar-blind ultraviolet photoelectric tube capable of working at a high temperature of 250°C, in particular to a high-temperature solar-blind ultraviolet phototube and a manufacturing method thereof. Background technique [0002] Modern warfare is a high-tech war, and it is particularly important to fight for air supremacy and long-range strikes. A large number of excellent performance fighter groups and missiles are the main tools for air strikes, and the normal and stable operation of aero engines plays a very important role. At present, fighter jets in developed countries in the United States and Europe have adopted photoelectric detection systems to monitor the working conditions of aero engines, and solar-blind ultraviolet phototubes are an indispensable key component in this detection system. At present, the general working temperature in the field of ultraviolet phototubes...
