The large-scale pulse power device plays an important role in the radiation effect field and the extreme physical environment construction, and with the increase of the current application requirements, the construction of the large-scale pulse power device with higher voltage (several MV to several tens MV) and larger current (several MA to several tens MA) is more urgent. In order to achieve the above objectives, the technical route for building next generation large pulse power devices is based on the principle of induced Voltage superposition, such as iva (inductive Voltage adder) and ltd (linear transducer driver), and is characterized by adopting a modular design, which is easy to expand to improve the power level of the device.
As the secondary of the induction voltage superposition type device, the magnetic insulation transmission line is a key device for high-power pulse superposition and transmission, and the basic principle is as follows: when the local field intensity of the transmission line can exceed the electron emission threshold (100-300kV/cm) of the cathode surface, the cathode surface explodes to emit electrons, and when the current is high enough, the emitted electrons make spiral motion under the action of the self-magnetic field and then return to the cathode, and at the moment, the magnetic insulation state is achieved. The magnetic insulation transmission line has the remarkable advantages of low inductance, ultrahigh power transmission, convergence and the like, so that the magnetic insulation transmission line is widely applied to the construction of pulse power devices.
