Abstract

The utility of the magnetically insulated transmission line oscillator (MILO) as a high power microwave source depends on how efficiently power can be extracted from it. We have designed a slow-wave stepped transformer for the purpose of axially extracting microwave power from a 3. 6 GHz coaxial MILO. The slow-wave transformer design was optimized using particle-in-cell simulation and tested in experiments performed on the HPM Simulation Division''s GEMINI and GYPSY water Blumlein pulse power sources. in this paper we summarize the slow-wave stepped transformer design and describe MILO axial power extraction experiments which yielded up to 300 MW of radiated power. 1.
