论文摘要
使用CR-39轨道检测器绝对校准BAS-TR图像板（IP）的响应，用于高线性能量转移（LET）AU离子高达$ \ sim $ 1.6 GEV（8.2 MeV/nucleon），这是由高功率激光器加速的。校准是通过使用高分辨率的汤森抛物线光谱仪来进行的，该光谱仪允许分辨出具有高度离子化状态的Au离子高达58 $^+$。通过拟合不同离子能量的光刺激发光（PSL）来获得响应函数，这与IIP在IP的活性层中停止的预期相一致。这种校准将允许量化高能Au离子的离子能谱，这对于进一步研究重离子束的激光加速度非常重要。
The response of the BAS-TR image plate (IP) was absolutely calibrated using CR-39 track detector for high linear energy transfer (LET) Au ions up to $\sim$1.6 GeV (8.2 MeV/nucleon), accelerated by high-power lasers. The calibration was carried out by employing a high-resolution Thomson parabola spectrometer, which allowed resolving Au ions with closely spaced ionization states up to 58$^+$. A response function was obtained by fitting the photo-stimulated luminescence (PSL) per Au ion for different ion energies, which is broadly in agreement with that expected from ion stopping in the active layer of the IP. This calibration would allow quantifying the ion energy spectra for high energy Au ions, which is important for further investigation of the laser-based acceleration of heavy ion beams.
