A '''linear transformer driver''' (LTD) is an annular [[Series and parallel circuits#Parallel circuits|parallel]] connection of switches and [[capacitor]]s designed to deliver rapid high [[Power (physics)|power]] pulses. The LTD was designed at the Institute of High Current Electronics (IHCE) in [[Tomsk]], Russia. The LTD is capable of producing high current, up to 1 megaamp (10<sup>6</sup> amps), pulses with a risetime of less than 100 ns. This is an improvement over [[Marx generator]] based [[pulsed power]] devices which require pulse compression to achieve such fast risetimes. It is being considered as a driver for [[z-pinch]] based [[inertial confinement fusion]].
[[Sandia National Laboratory]] is currently investigating a z-pinch as a possible ignition source for inertial confinement fusion. On its "[[Z machine]]", Sandia can achieve dense, high temperature plasmas by firing fast, 100
Sandia's roadmap includes another future Z machine version called ZN (Z Neutron) to test higher yields in fusion power and automation systems. ZN is planned to give between 20 and 30 MJ of hydrogen fusion power with a shot per hour thanks to Russian Linear Transformer Driver (LTD) replacing the current Marx generators.<ref>[http://www.sandia.gov/LabNews/070427.html Rapid-fire pulse brings Sandia’s Z method closer to goal of developing high-yield fusion reactor], Sandia's press release (April 27 , 2007).</ref> After 8 to 10 years of operation, ZN would become a transmutation pilot plant capable of a fusion shot every 100 seconds.<ref>[http://www.prod.sandia.gov/cgi-bin/techlib/access-control.pl/2006/067148.pdf Z-Inertial Fusion Energy: Power Plant Final Report FY 2006], Sandia Report SAND2006-7148 (October 2006).</ref>
