Pushing the frontiers of high-voltage pulse technology (ETF.6485)

Project nummer: etf6485

Omschrijving van het onderzoek

Extreme high electric field-strengths of the order Gigavolt per meter (GV/m) can be achieved (without breakdown to occur) by using ultrashort high-voltage pulses with a time duration of the order nanoseconds. For this purpose we develop a novel, tabletop transmission line transformer which is able to create high-voltage pulses with an amplitude up to a Megavolt and a duration of a nanosecond. Subsequently, these pulses will be sharpened by a photoconductively switched air-filled spark gap, which is switched by a high-power femtosecond laser. This way, the high-voltage pulses out of the transformer are reshaped to pulses with a very fast rise time (order ps) and almost no shot-to-shot time variation (jitter). This approach makes it possible to synchronize high-voltage pulses more accurate. Possible applications of photoconductively switched ultrashort pulses include the creation of broadband, high-intensity terahertz radiation as a harmless alternative to X-rays for medical and security purposes. Also research in the field of bioelectrics can be extended by using the higher voltages with faster rise times. Our purpose is to use these ultrafast high-voltage pulses to develop a new type of electron accelerator and its diagnotics.
