Abstract (en)

[origin: FR2778306A1] The invention concerns a device for emitting X-rays comprising a microwave source (60), a resonance chamber (10) containing a tightly confined gas volume, a magnetic structure (50, 51) defining an electron confinement geometric zone (H) wherein electrons move at high velocity and at least a target (90, 91, 92) placed on an electron trajectory to emit X-rays. The invention is characterised in that the target is offset relative to a median region (M) of the geometric confinement zone (H).
