Here, we extend flatbed scanner calibrations of GafChromic EBT3, MD-V3, and HD-V2 radiochromic films using high-precision x-ray irradiation and monoenergetic proton bombardment. By computing a visibility parameter based on fractional errors, optimal dose ranges and transitions between film types are identified. The visibility analysis is used to design an ideal radiochromic film stack for the proton energy spectrum expected from the interaction of a petawatt laser with a cryogenic hydrogen jet target.

优化辐射变色薄膜堆栈以诊断高通量激光加速质子束

在这里，我们使用高精度 X 射线辐射和单能质子轰击扩展了 GafChromic EBT3、MD-V3 和 HD-V2 放射变色薄膜的平板扫描仪校准。通过基于分数误差计算可见性参数，确定了最佳剂量范围和胶片类型之间的过渡。可见性分析用于设计理想的放射致变色薄膜堆栈，其质子能谱来自拍瓦激光器与低温氢射流目标的相互作用。
