Abstract
Linear transformer drivers can be used as fast pulsed-power generators to produce and study matter under extreme conditions, with densities larger than 10 times that of solids. While its scientific investigations can start in a laboratory, it will eventually require a source of x rays that can be provided only by specialized light source facilities. When relocation becomes a necessity, a compact, modular design is clearly advantageous. This paper shows how nested transmission lines can reduce considerably the footprint of MA-class pulsed-power generators based on linear transformer driver technology.
Highlights
While linear transformer driver (LTD) [1,2,3] systems have been around for decades [4], new designs using fast, high-voltage (V ∼ 100 kV) capacitors make them a competitive alternative to Marx-bank generators
In fast Marx-bank designs, the module transmission lines are replaced by pulse-forming lines and intermediate switches, required to compress a microsecond current pulse down to 100 ns
We found that the current evolution is overall consistent for both wrapped [shown in Fig. 7(a)] and conical [shown in Fig. 7(b)] transmission lines
Summary
While linear transformer driver (LTD) [1,2,3] systems have been around for decades [4], new designs using fast (trise ∼ 100 ns), high-voltage (V ∼ 100 kV) capacitors make them a competitive alternative to Marx-bank generators. Initiating fusion reactions [9] using a fast Z pinch [10] with a load inductance on the order of 10 nH requires a current of 10 MAwith a current rise time of 100 ns Under these conditions, the peak voltage will be at least 1 MV. Reach 1 MV, and in parallel, to deliver 10 MA to the load This design requires two kinds of transmission line [11]. In fast Marx-bank designs, the module transmission lines are replaced by pulse-forming lines and intermediate switches, required to compress a microsecond current pulse down to 100 ns. While current rise time differs slightly between the two models, it is necessary to use the electromagnetic code to compute the strength of the electric field inside the transmission line gap to optimize the anode-cathode separation
