Description
Technical Field
The invention relates to the field of accelerator filament power supply, which can be widely applied to medium and low energy accelerator filament power supply systems.
Background
The filament temperature of the accelerator is directly related to the quantity of electrons emitted by the electron gun of the accelerator, and the size of the beam current of the accelerator can be changed by changing the filament temperature of the electron gun. In engineering, the power supply of the cathode filament of the accelerator is connected with a high potential, the voltage control end is connected with a low potential end controller, and the key problems of high and low potential difference and insulation safety must be overcome to realize that the control of the filament power supply voltage is not influenced by the energy change of the accelerator.
The large potential difference between high potential and ground potential, such as electron accelerator, the voltage is up to hundreds of kilovolts, even up to several megavolts, generally speaking, transporting charge to high potential end, needs to overcome the large potential difference, and consumes large energy, such as the high voltage power supply of electron accelerator will overcome the large potential difference, transporting electron to high voltage end, then electron gun emitting electron, in vacuum, electron returning to low voltage end from high voltage end, the electron at this time obtains energy consistent with potential difference, the moving speed is close to light speed. Such high voltage power supplies are bulky and expensive.
There are also various ways in engineering to provide electrical power to an electron gun. Firstly, utilize the motor to drive the insulator spindle at the low potential end, drive the generator electricity generation at the high-voltage end through the insulator spindle. And secondly, a plurality of isolation transformers are utilized and connected in series to gradually increase the potential to the rated high potential. And an insulating core transformer is utilized to gradually raise the potential of the iron core to a rated high potential for power supply and the like. These devices are complex in structure, and are too bulky and costly to use in medium and low energy accelerators.
