Sandia National Laboratories has been operating the Mykonos linear transformer driver (LTD) in a five-cavity configuration since 2014. The machine operates at 1 MA output current, 500 kV output voltage, with a 10-90% current rise time of 85 ns, which enables small scale physics and engineering pulsed power experiments.
The Mykonos Facility is located in Tech Area IV at Sandia National Laboratories. The high bay has a square footage of 4054 ft and houses the pulsed power driver and an EMI shielded control room. The Mykonos pulsed power driver consists of 5, three-meter-diameter LTD cavities. Each cavity contains 36 LTD bricks comprised of a 200 kV multi-gap switch and two 40 n capacitors per brick. The five cavities are triggered sequentially and drive a matched impedance load.
The experimental work area has a rectangular square footage of 12 × 8 ft and is fully enclosed and certified as a laser control area (LCA). The target chamber is mounted to the vacuum insulator at a height of 6 ft (center line), and is surrounded by a 8 × 7 ft optical breadboard along the wall that allows for flexible diagnostics configurations.
