Linac based X-ray sources are commonly used by customs officers and homeland security worldwide to scan the contents of shipping containers and trucks for illicit materials and goods, as well as dangerous materials. The linac consists of a small particle accelerator and a target. Modern scanning systems require more flexible X-ray sources to provide better scanning of objects where the X-ray output can be closely matched for each object to be scanned, known as image driven optimisation. However such flexible X-ray sources are not currently available.Lancaster University and STFC have recently developed a compact controllable X-ray source as part of the PNPAS scheme. We propose to improve the engineering design of this linac to increase its technology readiness level as well as upgrading this linac to a higher beam energy, 3 MeV, and implement a sophisticated control system developed for high energy physics accelerators to allow the development of a flexible X-ray source suitable for image driven optimisation.The linac is also significantly smaller than conventional linacs, allowing a reduction in weight that improves themanoeuverability of the linac.

基于LINAC的X射线资源通常由全球海关官员和国土安全部通常使用，以扫描运输集装箱和卡车的内容物中的非法材料和商品以及危险材料。 Linac由一个小的粒子加速器和一个目标组成。现代扫描系统需要更灵活的X射线源，以更好地扫描X射线输出可以与每个对象进行扫描的对象，以扫描每个对象，称为图像驱动的优化。然而，当前尚不可用的这种灵活的X射线来源。LancasterUniversity和STFC最近开发了一个紧凑的可控X射线源，作为PNPAS方案的一部分。我们建议改善该线纳纳克的工程设计，以提高其技术准备性水平，并将该Linac升级到更高的光束能量，3 MEV，并实施为高能量物理加速器开发的复杂控制系统，可以开发适合图像驱动优化的柔性X射线源。与传统的Linac相比，linac允许较小的linac linac blinak sive in Linac showcluctue shownaks blinac blinac blinaC syrove shownaks a linac blinac shownaks s blunac shownain show blinac shownak s inlinac shownain shownain syne conventure shownac shignal的范围也会大大更小。
