| 内容記述 | A powerful hard x-ray source based on laser plasma interaction is developed.By introducing the kHz, 800nm pulses onto a rotating molybdenum(Mo) disk target,intense Mo Kα x-rays are emitted with suppressed bremsstrahlung background.Results obtained with different laser intensities suggest that the dominant absorption mechanism responsible for the high conversion efficiency is vacuumheating(VH). The high degree of spatial coherence is verified. With the high average flux and a source size comparable to the laser focus spot,absorption contrast imaging and phase contrast imaging ar ecarried out to test the imaging capability of the source.Not only useful for imaging application,this compact x-ray source is also holding great potential for ultrafast x-ray diffraction(XRD) due to the intrinsic merits such as femtosecond pulseduration and natural synchronization with the driving lase rpulses. |
