极端宇宙空间观测站超压气球（EUSO-SPB 2）使命任务将发射两台定制的望远镜，这两台望远镜采用施密特光学系统，以测量PeV和EeV尺度的宇宙射线产生的大范围空气簇射的Čerenkov和荧光发射，并搜寻τ中微子。这两个望远镜都有1米直径的孔径和紫外/紫外可见光灵敏度。切伦科夫望远镜使用双焦镜段对准，以区分撞击相机的直接宇宙射线与来自望远镜外部的切伦科夫光。望远镜集成和实验室校准将在科罗拉多进行。为了估计集成望远镜的点扩散函数和效率，正在制造一个提供1米直径平行光束的测试光束系统。完全集成的仪器的端到端测试将在犹他州沙漠的黑暗地点进行，使用宇宙射线，恒星和人造光源。激光轨迹长期以来一直用于表征荧光检测器在该领域的性能。对于EUSO-SPB 2，预计将通过使用双动态激光雷达配置（其中激光器和望远镜都是可操纵的）对方法进行改进，包括对气溶胶衰减的校正。我们计划在2021年秋季和2022年春季进行这些现场测试，以适应EUSO-SPB 2计划于2023年在新西兰瓦纳卡发射。
The Extreme Universe Space Observatory Super Pressure Balloon (EUSO-SPB2) mission will fly two custom telescopes that feature Schmidt optics to measure Čerenkovand fluorescence-emission of extensive air-showers from cosmic rays at the PeV and EeV-scale, and search for τ-neutrinos. Both telescopes have 1-meter diameter apertures and UV/UV-visible sensitivity. The Čerenkov telescope uses a bifocal mirror segment alignment, to distinguish between a direct cosmic ray that hits the camera versus the Čerenkov light from outside the telescope. Telescope integration and laboratory calibration will be performed in Colorado. To estimate the point spread function and efficiency of the integrated telescopes, a test beam system that delivers a 1-meter diameter parallel beam of light is being fabricated. End-to-end tests of the fully integrated instruments will be carried out in a field campaign at dark sites in the Utah desert using cosmic rays, stars, and artificial light sources. Laser tracks have long been used to characterize the performance of fluorescence detectors in the field. For EUSO-SPB2 an improvement in the method that includes a correction for aerosol attenuation is anticipated by using a bi-dynamic Lidar configuration in which both the laser and the telescope are steerable. We plan to conduct these field tests in Fall 2021 and Spring 2022 to accommodate the scheduled launch of EUSO-SPB2 in 2023 from Wanaka, New Zealand.
