Abstract :
High energy density materials are being developed for use in pulsed power area, such as Transmission Line in pulse generator, symmetric Blumlein or asymmetric Blumlein in Dielectric wall Accelerator. The High energy density materials could reduce the device physical size and improve the device´s efficiency. The ceramics and polymer/ceramics composition have been studied in our lab. To increase the breakdown strength, the dielectric compositions are being developed based on glass, and Epoxy. The nano-technology has been used in glass composite for getting better electrical performance. The diameter of BaTiO3 powder adding in epoxy is about 2 to 4 micron. The test samples have been fabricated. The permittivitv of glass/BaTiO3 is over 400 and its field strengths over 100 kV/cm and 300 kV/cm under DC voltage and nanosecond pulses, respectively.
