通过使用定义良好的单能量、铅笔状、高能和强介子束，可以通过同时测量能量损失和多次散射，实现快速和元素选择性射线照相，以检测例如几公斤的U，这些U被屏蔽在厚铁容器中或隐藏在低z材料的2-3米内。这种理想的μ子束源可以通过卡车拖车运输，通过结合一个紧凑的400 MeV电子加速器用于光π/μ产生，一个超导螺线管用于全立体角π/μ捕获和传输，一个停在热钨金属中用于冷却高能μ+到亚ev μ+，最后一个紧凑的线性加速器用于快速加速到600 MeV。介绍了该方法的原理和一些细节。
By using a well-defined mono-energetic, pencil-like, high-energy and intense muon beam, one can realize, via simultaneous measurements of energy-loss and multiple-scattering, a quick and element-selective radiography to detect e.g. a few kg of U which is shielded in a thick Fe container or hidden within 2–3 m of low-Z material. A source of such an ideal beam of muons can be realized in transportable form via truck trailers, by combining a compact 400 MeV electron accelerator for photo π/μ production, a superconducting solenoid for full-solid-angle π/μ capture and transport, a stopping in hot tungsten metal for cooling of energetic μ+ to sub-eV μ+, and finally a compact linear accelerator for rapid acceleration to 600 MeV. Principle and some details are described.
