We have developed a novel discrimination methodology to identify ions in multispecies beams with similar charge-to-mass ratios, but different atomic numbers. After an initial separation by charge-to-mass ratios using co-linear electric and magnetic fields, individual ions can be discriminated by considering the linear energy transfer of ions irradiating a stimulable phosphor plate (Fujifilm imaging plate) by comparison with the Monte Carlo calculation. We apply the method to energetic multispecies laser-driven ion beams and use it to identify silver ions produced by the interaction between a high contrast, high intensity laser pulse; and a sub-micrometer silver foil target. We also show that this method can be used to calibrate the imaging plate for arbitrary ion species in the range of Z ≥ 6 with dE/dx > 0.1 MeV/μm without requiring individual calibration.

Fujifilm BAS-SR成像板中线性能量转移测量的离子种类鉴别方法

我们开发了一种新颖的鉴别方法来识别多物种束中具有相似荷质比但原子序数不同的离子。在使用共线电场和磁场按荷质比进行初始分离后，可以通过考虑离子照射可激发荧光板（Fujifilm 成像板）的线性能量转移与蒙特卡罗计算进行比较来区分单个离子. 我们将该方法应用于高能多物种激光驱动的离子束，并用它来识别由高对比度、高强度激光脉冲之间的相互作用产生的银离子；和亚微米银箔靶。我们还表明，该方法可用于校准 Z ≥ 6 范围内任意离子种类的成像板，dE/dx > 0。
