新型ABALONE光电传感器技术:真空完整性、内部抽吸和后脉冲的4年长期试验
The Novel ABALONE Photosensor Technology: 4-Year Long Tests of Vacuum Integrity, Internal Pumping and Afterpulsing
摘要:
ABALONE光电传感器技术(美国专利9064678 2015)能够通过提供现代且具有成本效益的替代产品来取代昂贵的80年历史的光电倍增管(PMT)制造。鲍鱼光电传感器仅由三个单片玻璃组件组成,通过我们的新型薄膜粘合剂密封在一起。在2013年,我们留下了一个早期的鲍鱼光电传感器原型完整的持续压力测试,在这里,我们报告其长期真空完整性。异常低的离子后脉冲率(约两个数量级低于光电倍增管)一直在不断改善。我们解释了这一成就的物理和技术原因。由于成本效益和特定的功能组合,包括低放射性水平,集成到大面积面板和鲁棒性,这项技术可以在基础物理,功能医学成像和核安全领域开辟新的视野。
英文摘要:
The ABALONE Photosensor Technology (U.S. Patent 9064678 2015) has the capability of supplanting the expensive 80 year old Photomultiplier Tube (PMT) manufacture by providing a modern and cost effective alternative product. An ABALONE Photosensor comprises only three monolithic glass components, sealed together by our new thin film adhesive. In 2013, we left one of the early ABALONE Photosensor prototypes intact for continuous stress testing, and here we report its long term vacuum integrity. The exceptionally low ion afterpulsing rate (approximately two orders of magnitude lower than in PMTs) has been constantly improving. We explain the physical and technological reasons for this achievement. Due to the cost-effectiveness and the specific combination of features, including low level of radioactivity, integration into large-area panels, and robustness, this technology can open new horizons in the fields of fundamental physics, functional medical imaging, and nuclear security.
