Abstract
Pulse power has expanded its regime in technological and application fields. The state-of-art of switching technology shifts the trend of pulse power from huge and single shot systems to compact and highly repetitive generators. This extends the pulse power application into industrial, environmental, biological, medical, and also scientific fields. The progress has enabled us to have high energy density plasma and/or well-defined extreme conditions with low cost and good reproducibility. Plasmas produced by compact pulse power devices are proposed as a new tool in small laboratories for high energy density physics and its applications.
