Abstract (en)
[origin: WO9724020A1] A method and a device for characterising an ionised medium using an electromagnetic radiation source having an ultrashort duration, wherein two synchronised main (10) and secondary (12) laser beams are used; an X-ray beam (15) is generated; the X-ray beam (15) is modulated and time-distributed to give a first X-pulse train (20) with a uniform time distribution; the ionised medium (21) is exposed to said pulses; the X-ray radiation re-emitted by the medium is detected (30); the signal generated in a transmission line (34) is discriminated by time sampling resulting from the illumination of a series of photoconductive elements (33) distributed along said line (34) by means of a second pulse train from the secondary beam (12) which has the same time distribution as the first; and the generated signals (36) are measured and recorded.
