Abstract

Radiography with multiple probe species offers the potential to extract additional information about a given object as compared to radiography with a single probe species. The flexibility for high-power, short-pulse lasers to accelerate a variety of particle species makes laser-driven sources an attractive option to achieve multi-probe radiography. However, crosstalk produced by each of laser-driven source may be responsible for substantial backgrounds on detectors, becoming a significant barrier to achieving simultaneous radiography. In this work, we describe measurements of and mitigation strategies against crosstalk between laser-driven radiography sources in experiments at the OMEGA EP laser.

激光驱动射线照相源之间串扰的缓解与鉴定

与使用单一探针进行射线照相相比，使用多种探针进行射线照相有可能提取特定物体的更多信息。高功率、短脉冲激光器可以灵活地加速各种粒子，这使得激光驱动源成为实现多探针射线照相术的一个极具吸引力的选择。然而，每个激光驱动源产生的串扰可能会在探测器上造成大量背景，成为实现同步辐射成像的一大障碍。在这项工作中，我们介绍了在 OMEGA EP 激光器实验中对激光驱动辐射源之间串扰的测量和缓解策略。

期刊介绍： High Energy Density Physics is an international journal covering original experimental and related theoretical work studying the physics of matter and radiation under extreme conditions. ''High energy density'' is understood to be an energy density exceeding about 1011 J/m3. The editors and the publisher are committed to provide this fast-growing community with a dedicated high quality channel to distribute their original findings. Papers suitable for publication in this journal cover topics in both the warm and hot dense matter regimes, such as laboratory studies relevant to non-LTE kinetics at extreme conditions, planetary interiors, astrophysical phenomena, inertial fusion and includes studies of, for example, material properties and both stable and unstable hydrodynamics. Developments in associated theoretical areas, for example the modelling of strongly coupled, partially degenerate and relativistic plasmas, are also covered.
