Detection of proton tracks with LiF Fluorescent Nuclear Track Detectors
AI总结：
本研究将LiF晶体基荧光核径迹探测器用于质子径迹探测，验证了1 MeV至约56 MeV能量下的探测效果，发现径迹为亮斑结构且亮度随LET升高而增强，与重离子探测趋势一致。
摘要：
基于LiF晶体的荧光核径迹探测器已被成功应用于探测质子诱发的径迹。实验使用能量范围从1 MeV到约56 MeV的质子进行辐照，在所有质子能量下均观测到了荧光径迹。这些径迹并非连续的，而是由一系列亮斑组成。亮斑之间的间隙会随着质子能量降低（电离密度升高）而趋于变窄。在研究的最高能量下，亮斑分布极为稀疏，无法将属于同一条径迹的亮斑关联起来。荧光径迹的强度（亮度）随LET（线性能量转移）的升高而增强，这与此前针对多种更重离子确立的趋势高度吻合。
英文摘要：
Fluorescent nuclear track detectors based on LiF crystals were successfully applied for detection of proton induced tracks. Irradiations were performed with protons with energy ranging from 1 MeV up to about 56 MeV and for all proton energies the fluorescent tracks were observed. The tracks are not continuous, but consist of a series of bright spots. The gaps between spots tend to narrow with decreasing proton energy (increasing ionization density). For the highest of the studied energies, the spots are scattered so sparsely, that it is not possible to link spots belonging to one track. The intensity (brightness) of the fluorescent tracks increases with the increasing LET and agrees well with the trend established earlier for various heavier ions.
