紫外波长范围的观测数据对解决多个天体物理学难题至关重要,因此从立方体卫星到未来旗舰级宜居世界天文台,有多项即将开展的紫外任务。除了新型仪器概念和改进的涂层,先进探测器是这些任务成功的关键。微通道板(MCP)探测器技术在紫外波段具有独特优势:兼具单光子计数能力与可见光盲特性。图宾根大学天文与天体物理研究所(IAAT)的紫外硬件团队正在开发一款可覆盖完整紫外波段的多功能MCP探测器系统。密封管型设计仅适用于118nm以上的波长,而开放型变体还可覆盖整个远紫外和极紫外波段,两者均采用相同的读出装置:共面交叉条阳极和基于FPGA的电子设备。本文中,我们报告该探测器的研制现状,展示最新的表征结果,并对其任务应用前景进行展望。

英文摘要

Observational data from the UV wavelength range is crucial to solve several astrophysical puzzles. Consequently, there are a number of upcoming UV missions from CubeSats up to the future flagship Habitable Worlds Observatory. Besides novel instrument concepts and improved coatings, advanced detectors are key for the success of these missions. The microchannel plate (MCP) detector technology offers a unique asset in the UV: the combination of single-photon counting and visible-blindness. The UV hardware group at the Institut für Astronomie und Astrophysik Tübingen (IAAT) develops a versatile MCP detector system that addresses the complete UV band. While a sealed-tube design is limited to wavelengths above 118\,nm, an open-face variant also covers the whole far- and extreme-UV. Both use the same readout: a coplanar cross-strip anode and FPGA-based electronics. In this contribution, we report on the status of the detector development, present the latest characterization results, and give an outlook on the mission prospects.
