Ironless betatrons - Short radiation pulse generators for roentgenography of fast-going processes

Pulsed roentgenography technique plays an important role in high-pressure physics researches employing shock waves, explosion energy magnetic cumulation, as well as in gasdynamics study of explosive facilities and other fields of investigations. Characteristics of a radiation generator and an image recorder which should meet high demands of explosive tests determine the technique capabilities. The required high spatial and temporal resolution limits the radiation pulse duration, irradiator dimensions and define the spectrum content of radiation used and the experiment geometry.
