Abstract:
Background High-energy flash X-ray photography has important applications in hydrodynamic experiments. As an important means of generating multi-pulse X-ray, the technical scheme of multi-pulse linear induction accelerators (LIA) in different countries have their own characteristics.
Purpose Based on requirements for the compactness, mobility, and high reliability of multi-pulse LIAs, the project team is exploring various novel multi-pulse power source technologies that can be used for multi-pulse LIAs.
Methods In this paper, a 100 kV four-pulse generation technology is explored, that is, a low-pressure pseudo-spark switch of tens of kV is used to drive the Blumlein line of tri-coaxial cables to generate multi-pulse high voltage, and the multi-pulse high voltage of tens of kV is superimposed by an induction voltage adder to generate a multi-pulse high voltage of 100 kV. The same four sets of pulse high-voltage generators are used to output multi-pulse high voltage of 100 kV, which are converged by a coaxial high-voltage diode to obtain four-pulse high-voltage output of 100 kV.
Results Simulation and experimental results show that the scheme could generate four-pulse high voltage of more than 100 kV with adjustable pulse interval.
Conclusions This compact and movable 100 kV four-pulse high-voltage generator is expected to become a new multi-pulse power source for multi-pulse LIAs.
