Abstract
A method and apparatus for downhole generation of non-radioactive, ionized radiation arranged so as to be able to generate reverberation, particularly X-ray and/or gamma radiation, from the surroundings of a borehole, wherein the method includes the steps of: exciting laser light in a multistage laser light booster by means of a pump-type laser light source so as to form a pulsed laser light, the incoming light energy being concentrated in restricted laser light pulses representing a higher amount of light energy than that of a continuous flux of laser light; forming a concentration of dissociated electrons in a vacuum chamber; focusing the pulsed laser light at a point in the concentration of dissociated electrons so as to form a field (wakefield) of pulsed electrons which, upon generation of Bremsstrahlung, emit ionized radiation to the surroundings, thereby forming a high-energy reverberation in the gamma and/or X-ray frequency range from the surroundings.
