Accelerators, Beams, and Repetitive Pulsed Power
Oral Presentation
The effects of core and copper losses on a novel magnetic compression based stepped impedance transmission line pulse generator circuit is presented. Design equations are derived and presented which take into account the current leakage into neighboring cells, losses due to magnetizing inductance currents, losses due to saturable cores and copper losses in the saturated inductance windings. It...

Biological, Medical, and Environmental Applications of Power Modulators
Oral Presentation
Pulsed power technology has been used for the ablation tumor. Considerable research shows that a high-strength unipolar pulse electric field can induce irreversible electroporation (IRE) on the cell membrane, which can effectively kill cells. But some scholars and doctors have found that muscle contractions occur during treatment, which are associated with the delivery of electric pulses....

Poster Presentation
A compact low impedance Marx generator was designed and tested. The generator consists of twelve stages and each stage utilizes two 18 nF 100 kV capacitors and four 1 nF 100 kV capacitors. When charged to the rated voltage of the capacitors the energy density of the complete generator is 15J/L. In the Marx generator different discharge periods form the capacitors added to the main circuit and...

Poster Presentation
Load current multipliers (LCMs) are specialized impedance transformers used in pulsed power generators to improve generator-to-load coupling at high power densities. These devices were recently demonstrated to increase load current by 70% on a 1 MA / 100 ns generator [1], but the concept has not been evaluated experimentally on higher current (>10 MA) generators. For example, plasma...

Accelerators, Beams, and Repetitive Pulsed Power
Oral Presentation
Repetitive pulse X-rays play an important role in the investigation of various physical processes in hydrodynamic experiments. Generation of repetitive pulse X-rays requires repetitively operating all solid state pulsed power source and X-ray diode.
As the testbed for repetitively operated diodes, a stacked Blumlein line (SBL) type pulsed power source (220 kV, 1 kA, 1 kHz) based on high...
