LTD technology of primary energy storage

LTD technology is being developed at HECI as an alternative to Marx generators. The basic unit of LTD storage is the LTD stage that is completely separate device build as a transformer with vacuum insulated secondary tum. Unlike in Marx scheme where the top stages get high voltage potential at erection, all the LTD stages keep ground potential during the shot. This means that the insulation inside the LTD stage has to be designed to withstand the charge voltage only thus allowing to reduce the thickness of insulation between the conductors that defines the inductance of the discharge circuit, reduce the pulse width and increase the output power of the generator. This feature of the LTD storage is attractive for ≪direct drive≫ systems operating in the 100 ns range without of intermediate power amplification. To the moment, the most powerful LTD stage delivers to the matched load a ~100 GW pulse with the current of ~1 MA rising in ~100 ns.
