Prof. Chenguo Yao (Chongqing University), Mr shoulong dong (Chongqing University)06/07/2016, 10:15Biological, Medical, and Environmental Applications of Power ModulatorsOral PresentationPulsed 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....Go to contribution page

Hongwei Liu (Institute of Fluid Physics)06/07/2016, 10:45Repetitive Pulsed Power Systems, Repetitive Pulsed Magnetics, Accelerators, Beams, High Power Microwaves, and High Power Pulse AntennasPoster PresentationA 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...Go to contribution page

George Laity (Sandia National Laboratories)06/07/2016, 11:00Repetitive Pulsed Power Systems, Repetitive Pulsed Magnetics, Accelerators, Beams, High Power Microwaves, and High Power Pulse AntennasPoster PresentationLoad 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...Go to contribution page

Jianqiang Yuan (China Academy of Engineering Physics)06/07/2016, 11:45Accelerators, Beams, and Repetitive Pulsed PowerOral PresentationRepetitive 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...Go to contribution page
