**Silveray** (SilverRay Ltd) is a start-up company whose primary goal is to exploit the technology developed in large-area high-sensitivity broadband X-ray detectors to disrupt the current state-of-the-art in X-ray imaging, and associated applications. This proprietary technology has been demonstrated to be 2-3 orders of magnitude higher in its sensitivity than the conventional detectors, while being able to operate at low voltage, and with excellent conformability to non-flat surfaces. The sensitivity of the detector material to specific X-ray energies of technology interest improves from approximately 100 times to over 1000 times per volume thickness of the state-of-art detector with increasing X-ray energy.The active detector material that has been patent-protected consists of an 'X-ray sensitive ink' containing an interpenetrating network of organic material and inorganic nanoparticles. The 'X-ray sensitive ink' can be used to coat films over any substrate, removing existing constraints for developing flexible detectors. Thus far, small area detectors (area < 1 cm2) have been developed and proven, with scale-up to larger sizes now ongoing within the company thanks to an InnovateUK SMART grant and a first round of VC funding.The next challenge is to roll-out this technology for a diverse range of applications spanning from non-destructive testing (NDT) of industrial products to defence (border and portable security), in-line quality inspection of food & pharmaceutical products (including beverages, grocery products, active component quantities/quality in pills), and medical (including dental and cancer treatment to achieve better patient outcomes).The **vision** for the company is to produce a market-validated printable high-performance direct conversion X-ray detector for applications across multiple disciplines. Challenges lie in developing a manufacturing process for producing a uniform mixture and depositing it in a thick film across the device, to ensure consistency in performance across the detector (pixel-to-pixel). Characterisation work within the project will give the company a better understanding on how to optimise the X-ray sensitive ink and its fabrication processes across large area detector planes necessary for each of the applications.The outcome of this project will be in facilitating the company's growth by providing exploitable routes to optimise the technology. The active and scalable nanoparticle-based layer of the direct-detector material will deliver high performance X-ray imagers with the required response times, higher sensitivity, with lower radiation dose, and be produced at considerably lower cost. This will ultimately lead to the development of a product range of higher specification marketable detectors across many sectors.

** Silveray **（Silverray Ltd）是一家初创公司，其主要目标是利用大区域高敏感性宽带X射线探测器开发的技术，以破坏X射线成像和相关应用程序中当前的最新技术。该专有技术已被证明其敏感性比传统探测器高2-3个数量级，同时能够以低电压运行，并且与非纤维表面具有出色的符合性。检测器材料对技术兴趣的特定X射线能量的敏感性从大约100次提高到最先进检测器的每体积厚度的1000倍以上，X射线能量的增加。由专利保护的活性探测器材料由含有X射线敏感的Ink构成，其中包含含有有机物和无内科生的有机材料的插入网络。 “ X射线敏感的墨水”可用于在任何底物上涂上膜，从而消除了开发灵活探测器的现有限制。 Thus far, small area detectors (area < 1 cm2) have been developed and proven, with scale-up to larger sizes now ongoing within the company thanks to an InnovateUK SMART grant and a first round of VC funding.The next challenge is to roll-out this technology for a diverse range of applications spanning from non-destructive testing (NDT) of industrial products to defence (border and portable security), in-line quality inspection of food & pharmaceutical products (including饮料，杂货产品，药丸中的活跃成分/质量）和医疗（包括牙科和癌症治疗以获得更好的患者结果）。该公司的**视觉**是为在多个学科的应用中生产市场验证的可验证的可打印高性能直接转换X射线探测器。挑战在于开发制造过程，以生产均匀的混合物并将其沉积在整个设备的厚膜中，以确保整个检测器的性能一致（像素到像素）。项目内的表征工作将使公司更好地了解如何在每个应用程序所需的大面积检测器平面上优化X射线敏感的墨水及其制造过程。该项目的结果将通过提供优化技术的可利用路线来促进公司的增长。直接检测器材料的有源且可扩展的纳米颗粒层将提供高性能X射线成像仪，其响应时间较高，较高的灵敏度，较低的辐射剂量，并以相当低的成本生产。这最终将导致许多领域的较高规格可销售探测器的产品范围。
