The Voitenko compressor is a shaped charge adapted from its original purpose of piercing thick steel armour to the task of accelerating shock waves.
When the shaped charge detonates, most of its energy is focused on the steel plate, driving it forward and pushing the test gas ahead of it.
[8][9] A further extension of this technology is the explosive diamond anvil cell,[10][11][12][13] utilizing multiple opposed shaped-charge jets projected at a single steel-encapsulated fuel,[14] such as hydrogen.
The fuels used in these devices, along with the secondary combustion reactions and long blast impulse, produce similar conditions to those encountered in fuel-air and thermobaric explosives.
The other successful method was using a miniature Voitenko-type compressor, where a plane diaphragm was driven by the implosion wave into a secondary small spherical cavity that contained pure deuterium gas at one atmosphere.
