Development of the ultra-fast LTD stage

The technology of the fast LTD stages is proposed for 1 MV driver with the goal to get a 60 ns pulse width at 80 % of peak voltage in the diode. For this driver a new LTD-100R stage is designed consisting of 20 GA 35389 capacitors. A 1 MV driver will include 7 such stages in series and provide 1 MV, 125 kA pulse in a critically matched load. The footprint of the whole system is ∼1.75 m². The report includes the design of the new stage and results of the tests.
