Design and experiments of solid-state pulse forming lines for dielectric wall accelerator
摘要
Abstract
The solid-state pulse forming lines (PFL)of CaO-TiO2-Al2 O3 composite ceramic are designed and manufactured for the dielectric wall accelerator.The PFL’s geometric parameters are 300 mm long,15 mm wide,1mm thick of ceramic dielec-tric and 280 mm long,2 mm wide of silver electrode.The electrical parameters are 23.5 relative dielectric constant,about 26 Ωcharacteristic impedance,4.5 ns characteristic time,20 kV/mm and 25 kV/mm breakdown field strength for DC and pulsed high voltage.The solid-state PFL’s design gives consideration to operating requirement of photoconductive semiconductor switches (PCSS),design parameters of high gradient insulator,charged particle beams transport and accelerator’s structural design.Com-bined with the PCSS,the experimental research of solid-state Blumlein PFL is performed.The solid-state Blumlein PFL could output about 23 kV pulsed voltage on the load under about 25 kV pulsed voltage.关键词
