1-MA Linear Transformer Driver (LTD) cavities as building blocks for ICE, ICF, and IFE drivers

摘要

Sandia in collaborations with a number of other institutions, is developing a new paradigm in pulsed power technology: the Linear Transformer Driver (LTD) technology. This approach can provide very compact devices that can deliver very fast high current and high voltage pulses. The output pulse rise time and width can be easily tailored to the specific application needs. We have extensively tested several induction LTD flat doughnut-shaped cavities which are 3m in diameter and have a 1.8 m bore and only ∼20 cm thickness, but they can deliver 0.1 TW, 70 ns rise time pulses to a matched ∼ 0.1 Ohm load. Experiments with a 1 TW Inductive Voltage Adder (IVA), which includes 10, 1-MA LTD cavities connected in series, are in preparation at MYKONOS LTD Laboratory in Sandia National Laboratories, Albuquerque, NM. This MYKONOS voltage adder will be the first ever IVA built with a transmission line insulated with de-ionized water. We present the design and experimental results of the first two-cavity water isolated voltage adder with a liquid salt solution resistive load. This is the first step towards the assembly of a ten cavity voltage adder.
