FIELD: physics.;SUBSTANCE: invention relates to X-ray engineering. A radiation source (19) for generating X-rays for analysing an object (16) comprises a first carbon nanotube (1) on a first substrate (3) for emitting first electrons (28) and a second carbon nanotube (2) on a second substrate (4) for emitting second electrons (29); a target (13); a focusing unit (7, 9) for focusing first and second electrons on the target to generate first X-ray photons having a first trajectory (14) and second X-ray photons having a second trajectory (15). The focusing unit is adapted to be controlled such that the first and second trajectories spatially overlap before reaching the analysed object such that the trajectories of the first and second X-ray photons are distinguished from each other.;EFFECT: high resolution of the radiation source and efficiency of imaging.;12 cl, 6 dwg
