Process and device for the production of radiations

The apparatus described includes: a device for producing a relativistic electron beam of not less than 3 MeV energy; a target plasma chamber containing a high density gas; a high Z substance located in the target plasma chamber; a device for ionizing the high density gas in order to produce a high density plasma; a device to trigger off convection oscillations in the plasma under the effect of applying the relativistic electron beam. The energy from the electron beam is deposited in the plasma to heat it up to temperatures corresponding to several kilovolts, the effect of which is to heat up the high Z substance and produce an intense source of radiation
