Abstract

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.
