用CR-39径迹探测器对高线性能量转移Au离子进行了绝对校准，测量范围为1.6 GeV（8.2 MeV/核子），用高功率激光加速。通过采用高分辨率汤姆逊抛物线光谱仪进行校准，该光谱仪允许分辨具有高达58+的紧密间隔的电离状态的Au离子。通过拟合不同离子能量下每个Au离子的光激励发光得到响应函数，这与离子停止在IP的活性层中的预期大致一致。这种校准将允许量化的高能Au离子的离子能谱，这是重要的，为进一步研究的重离子束的激光加速。
The response of the BAS-TR image plate (IP) was absolutely calibrated using a CR-39 track detector for high linear energy transfer Au ions up to ∼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 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.
