Abstract :
In this report, a new super fast LTD stage prototype, able to deliver a 75 ns FWHM voltage pulse into a ∼(0.5–0.6) Ohm matched load with ∼20 GW power, is presented. This stage is designed without peaking capacitors to increase its reliability. It includes 32 GA35436 (8 nF, 100 kV) storage capacitors, 16 multi gap switches, and a magnetic core made with reduced thickness of the ferromagnetic iron tape (50μm) to limit the current losses due to vortical currents. This prototype stage was specifically designed with an ellipsoidal vessel to allow the use of compressed gas (SF6, SF6/dry air mixtures, and pure dry air up to 6 ata pressure), or transformer oil, as the insulating medium.
