In X-ray laser plasma diagnostics, fast and accurate integrated alignment is essential, yet existing methods are not only limited in accuracy but also time inefficient. An integrated alignment method of X-ray diagnostic systems with accurate, rapid and repeatable characteristics was proposed in this paper. First, the method establishes precise object-image relationship of X-ray diagnostic system based on laboratory X-ray imaging experiments, and then the relationship is indicated by the ball pointer and the image indication module. To achieve high resetting accuracy, the ball pointer and image indication module are coupled to the X-ray diagnostic system by linear guides. Finally, the X-ray diagnostic system is directly switched to the online environment at the laser facility by the indication of the ball pointer and image indication module. The paper presents the optical design, mechanism structure and experimental result of the integrated alignment method taking HOPG spectrometer for copper emission spectrum as an example. The method has been applied in the adjustments of X-ray diagnostics systems for several physics experiments in multiple laser facilities.
Precise X-ray Imaging diagnostics to acquire the plasma state and its evolution plays an important role in basic researches such as inertial confinement fusion (ICF), high energy density physics (HEDP), and another ultrafast phenomenon. The plasma signals with the characteristics of small scale, rapid evolution and complex spectrum requires the X-ray diagnostics optics to have high spatial resolution and collection efficiency, as well as certain spectral resolution. The multilayer Kirkpatrick–Baez (KB) microscope is a common X-ray optics to obtain high spatial, collecting efficiency or spectral resolution. Coupling multichannel KB microscope with the framing camera, the temporal evolution behavior of the ultrafast plasma can be recorded. The paper mainly presents our latest research on two-energy sixteen-channel multilayer KB microscope for double-cone ignition (DCI) experiments, including its optical and multilayer design. By high-resolution backlighting and self-emission imaging using two-energy multichannel KB microscope, plasma information related to density and temperature can be realized simultaneously.
