This SBIR Phase II research project proposes to develop and commercialize advanced high- resolution ceramic microchannel plates (s-MCPs) for applications in low- and night vision devices, scientific detectors and biomedical imaging. Conventional glass-fiber MCP technology has reached its fundamental limits in spatial and temporal resolution, fixed pattern noise, high count rate capabilities, thermal performance, yield and reproducibility, stability and lifetime. This is a unique approach based on nanoporous ceramics, which allows reaching ultra-high sub-micron resolution. Due their ceramic nature, the proposed s-MCPs are capable of processing temperatures up to 1000 degrees celsius, enabling direct integration of advanced photocathodes for expanded spectral range and sensitivity, and are also expected to have greater lifetime than those produced with existing methods. In addition ceramic s-MCPs can be produced at a much lower cost than glass MCPs. A robust ceramic structure with the required dimensions and resistance has been developed. The remaimimg challenge is to fabricate functional s-MCP prototypes from this structural material, along with validation of s-MCP performance.The expected result of the proposed work is a manufacturing technology for production of commercially viable sub-microchannel plate intensifiers with better performance, longer lifetime and lower cost. This could open up new opportunities in the development of the next generation particle and photon detection systems for the infrared, UV, x-ray and gamma ray astrophysics applications. Spin-off applications for ceramic MCPs include "lobster eye" optics for x-ray detectors as well as gas avalanche detectors. Commercial applications include detectors for high-energy physics, scientific instrumentation, biomedical imaging, commercial satellite mapping, vision augmentation, as well as consumer night vision products.

该SBIR二期研究项目建议开发和商业化先进的高分辨率陶瓷微通道板（s-MCPs），用于低视和夜视设备，科学探测器和生物医学成像。传统的玻璃纤维MCP技术在空间和时间分辨率、固定模式噪声、高计数率能力、热性能、产量和再现性、稳定性和寿命方面已经达到了基本极限。这是一种基于纳米多孔陶瓷的独特方法，可以达到超高的亚微米分辨率。由于其陶瓷性质，所提出的s- mcp能够处理高达1000摄氏度的温度，从而能够直接集成先进的光电阴极，以扩大光谱范围和灵敏度，并且预计比现有方法生产的光电阴极具有更长的寿命。此外，陶瓷s- mcp可以以比玻璃mcp低得多的成本生产。已开发出具有所需尺寸和电阻的坚固陶瓷结构。剩下的挑战是用这种结构材料制造功能性s-MCP原型，以及s-MCP性能的验证。该工作的预期结果是为生产性能更好、寿命更长、成本更低、具有商业可行性的亚微通道板增强剂提供了一种制造技术。这可能为红外、紫外、x射线和伽马射线天体物理学应用的下一代粒子和光子探测系统的发展开辟新的机会。陶瓷mcp的衍生应用包括用于x射线探测器和气体雪崩探测器的“龙虾眼”光学器件。商业应用包括高能物理探测器、科学仪器、生物医学成像、商业卫星测绘、视觉增强以及消费者夜视产品。
