Abstract
An electron gun detecting device comprises the components of: a flange, a carriage, a cooling tube, a detecting base, magnets, electrodes, conductive platinum sheets and porcelain rods. The cooling tube is L-shaped. A coolant inlet port and a coolant outlet port penetrate through the flange. The detecting base is arranged on the cooling tube. The part of the cooling tube on the detecting base bends to outside of the detecting base. The detecting base has a hollow structure with an upper opening. Two ends of the detecting base, which are parallel with the flange, are respectively provided with a magnet. The flange is provided with the electrodes. The carriage is fixed on the flange. The porcelain rods are fixed on the carriage. The conductive platinum sheets are fixed on the porcelain rods. The electron gun detecting device has a simple structure. An added cooling system can greatly reduce effect of high temperature caused by high voltage in detection to the electron gun, thereby realizing accurate data result and ensuring high stability of detecting technology.
