下一代强、短脉冲激光设施需要新的高重复率诊断来检测电离辐射。我们设计了一种新型基于闪烁体的离子束轮廓仪，能够测量多个离散能量范围的离子束横向轮廓。已经针对一系列质子能量和通量研究了四种常见塑料闪烁体的光学响应和发射特性。闪烁体光输出（对于 1 MeV > Ep< 28 MeV）被发现与质子能量具有非线性缩放关系，但对入射通量具有线性响应。尽管需要进一步的校准工作来表征典型高强度激光-等离子体相互作用的高通量、短脉冲持续时间条件下的总系统响应和限制，但原型诊断的初始测量已经成功。
Next generation intense, short-pulse laser facilities require new high repetition rate diagnostics for the detection of ionizing radiation. We have designed a new scintillator-based ion beam profiler capable of measuring the ion beam transverse profile for a number of discrete energy ranges. The optical response and emission characteristics of four common plastic scintillators has been investigated for a range of proton energies and fluxes. The scintillator light output (for 1 MeV > Ep< 28 MeV) was found to have a non-linear scaling with proton energy but a linear response to incident flux. Initial measurements with a prototype diagnostic have been successful, although further calibration work is required to characterize the total system response and limitations under the high flux, short pulse duration conditions of a typical high intensity laser-plasma interaction.
