摘要

在减少辐射剂量的方法中(增加辐射源到人的距离,减少在辐射场中停留的时间,降低辐射源的辐射剂量率),屏蔽电离辐射源起着重要作用。目前,筛网的使用受到选材少、使用不便的限制,使其操作、安装更换或拆卸变得复杂。本文用线性近似的方法分析了含有单杂质和双杂质(缺陷)的一维力链中平面波的传播。确定了控制方程的解析解和入射辐射反射系数和透射系数的求值算法。在相移方面,建立了类似于惰性气体原子散射电子时的Ramsauer-Townsend效应的非均匀链(含双杂质)透明模多模产生的频率判据。所得的理论结果与从其他来源获得的数据一致。讨论了在离散微机械(颗粒)系统中应用太赫兹辐射透射光谱进行结构诊断和非均匀性、杂质和缺陷检测的可能性。特别是对不同堆积程度的颗粒材料样品的太赫兹辐射散射的初步实验数据,从低堆积到密集堆积,清楚地表明了透射率与堆积程度的依赖关系,并形成了相应的光谱带结构。本文还讨论了该方法在亚毫米级光子电路元件基上的应用。

Diagnosis of inhomogeneous one-dimensional discrete chains by photon scattering
Among the ways to reduce radiation doses (increasing the distance from the source to the person, reducing the time spent in radiation fields, reducing the radiation dose rate of the source) an important role is played by shielding the source of ionizing radiation.Currently, the use of screens is limited by the small selection of materials and the inconvenience of their use, which complicates their operation, installation and replacement, or disassembly.The propagation of a plane wave in a one-dimensional force chain with Hertzian contacts is analyzed in a linear approximation for cases with the presence of incorporated single and double impurities (defects). The algorithm of analytical solution of control equations and finding of reflection and transmission coefficients of incident radiation is determined. In terms of phase shifts, the frequency criterion of multi-modes of generation of transparent modes for inhomogeneous chains (with double impurities) similar to the Ramsauer-Townsend effect in the scattering of electrons by inert gas atoms is established. The obtained theoretical results are consistent with the data obtained from alternative sources. Possibilities of application of terahertz spectroscopy of radiation transmission for structural diagnostics and detection of in homogeneities, impurities and defects in discrete micro-mechanical (granular) systems are discussed. In particular, preliminary experimental data on scattering of terahertz radiation on samples of granular materials with different degrees of packing, from low to densely packed, which clearly indicate the dependence of the transmittance on the degree of packing and the formation of the corresponding band structure of spectra. The obtained results are also discussed in terms of applications to the creation of the element base of photonic circuitry in the sub millimeter range using decorated with impurities and structured low-dimensional discrete power circuits.
