We have designed and prototyped the process steps for the batch production of large-area micro-channel-plate photomultipliers (MCP-PMT) using the "air-transfer" assembly process developed with single LAPPDTM modules. Results are presented addressing the challenges of designing a robust package that can transmit large numbers of electrical signals for pad or strip readout from inside the vacuum tube and of hermetically sealing the large-perimeter window-body interface. We have also synthesized a photocathode in a large-area low-aspect-ratio volume and have shown that the micro-channel plates recover their functionality after cathode synthesis. These steps inform a design for a multi-module batch facility employing dual nested low-vacuum and ultra-high-vacuum systems in a small-footprint. The facility design provides full access to multiple MCP-PMT modules prior to hermetic pinch-off for leak-checking and real-time photocathode optimization.

大面积皮秒光电探测器的空气转移生产方法

我们已经设计并原型化了批量生产大面积微通道板光电倍增管 (MCP-PMT) 的工艺步骤，该工艺步骤使用由单个 LAPPDTM 模块开发的“空气转移”组装工艺。提出的结果解决了设计坚固封装的挑战，该封装可以传输大量电信号以从真空管内部读取焊盘或条带，并密封大周长窗体接口。我们还合成了大面积低纵横比体积的光电阴极，并表明微通道板在阴极合成后恢复其功能。这些步骤为采用双嵌套低真空和超高真空系统的多模块批量设施设计提供了信息，占地面积小。
