Note: Compact Helical Pulse Forming Line For The Generation Of Longer Duration Rectangular Pulse
REVIEW OF SCIENTIFIC INSTRUMENTS(2012)
Abstract
The helical pulsed forming line (PFL) can generate longer duration rectangular pulse in a smaller length. A compact PFL using helical water line is designed and experimentally investigated. The impedance of the helical PFL is 22 Omega. The compactness is achieved in terms of reduction in length of the PFL by a factor of 5.5 using helical water PFL as compared to coaxial water PFL of same length. The helical PFL was pulsed charged to 200 kV using a high voltage pulse transformer in 4.5 mu s and discharged into the matched 22 Omega resistive load through a self-breakdown pressurized spark gap switch. The rectangular voltage pulse of 100 kV, 260 ns (FWHM) is measured across the load. The effect of reduction in water temperature on the pulse width is also studied experimentally. The increase in pulse width up to 7% more is observed by reducing the temperature of the deionized water to 5 degrees C. It will further reduce the length of the PFL and make the system small for compact pulsed power drivers. (C) 2012 American Institute of Physics. [http://dx.doi.org/10.1063/1.4728206]
