摘要
下一代气球载大口径亚毫米波望远镜（BLAST-TNG）是一台亚毫米波偏振计，设计用于在 24 天南极飞行中于 250、350 和 500 微米波段绘制星际尘埃与星系前景。BLAST-TNG 探测器阵列分别由 918、469 和 272 个 MKID 像素组成。像素由两具正交取向、交叉的线偏振敏感 MKID 天线构成。阵列被冷却至 300mK 以下温度，并通过闭循环 He 吸附制冷机结合 He 真空罐实现稳定。探测器通过第二代可重构开放架构计算硬件（ROACH2）与为 BLAST-TNG 定制的射频电子学组合读出。为读出并表征这些探测器而设计的固件与软件由 BLAST 团队围绕这些探测器从零构建，并已被 TolTEC 与 OLIMPO 等其他 MKID 仪器改造使用。我们概述这些系统，并深入阐述地基表征方法与实测在飞行性能。
