Abstract

We present the integration of a new calibration system into the Faint Intergalactic-medium Redshifted Emission Balloon-2 (FIREBall-2), which added in-flight calibration capability for the recent September 2023 flight. This system is composed of a calibration source box containing zinc and deuterium lamp sources, focusing optics, electronics, sensors, and a fiber-fed calibration cap with an optical shutter mounted on the spectrograph tank. We discuss how the calibration cap is optimized to be evenly illuminated through non-sequential modeling for the near-UV (191 to 221 nm) for spectrograph slit mask position calibration, electron multiplying charged-coupled device (EMCCD) gain amplification verification, and wavelength calibration. Then, we present the pre-flight performance testing results of the calibration system and their implications for in-flight measurements. FIREBall-2 flew in 2023, but did not collect calibration data due to early termination of the flight.

FIREBall-2 紫外气球望远镜飞行中校准系统

我们介绍了将新的校准系统集成到 "微弱星际-中红移发射气球-2（FIREBall-2）"的情况，该系统为最近于 2023 年 9 月进行的飞行增加了飞行中校准能力。该系统由包含锌和氘灯源的校准源箱、聚焦光学器件、电子器件、传感器以及安装在摄谱仪槽上带有光学快门的光纤馈电校准帽组成。我们将讨论如何通过非序列建模优化校准帽，使其均匀照射近紫外线（191 至 221 纳米），以进行摄谱仪狭缝掩膜位置校准、电子倍增电荷耦合器件（EMCCD）增益放大验证和波长校准。然后，我们将介绍校准系统的飞行前性能测试结果及其对飞行中测量的影响。FIREBall-2于2023年飞行，但由于飞行提前结束，没有收集到校准数据。
