DC Characterization of High Gradient Multilayer Insulators

reportActive / Technical Report | Accession Number: ADA635332 | Open PDF

Abstract:

We have developed a novel insulator concept that involves the use of alternating layers of conductors and insulators with periods less than 1 mm. We have demonstrated that these structures perform 2 to 5 times better than conventional insulators in long pulse, short pulse, and alternating polarity applications. We present new testing results showing exceptional behavior at DC, with gradients in excess of 110kVcm in vacuum.
