Abstract

The Compact SOLSTICE, a compact far and mid ultraviolet (FUV and MUV) spectrograph, flew on a sounding rocket on 18 June 2018 to validate and potentially calibrate the SOLar STellar Irradiance Comparison Experiment (SOLSTICE) onboard the Solar Radiation Climate Experiment (SORCE) spacecraft. This article reports the instrument design, the calibration of the FUV channel, and the FUV irradiance measurements. Irradiance measurements are compared to SOLSTICE showing agreement within the combined instrumental uncertainties at most wavelengths, including the H Lyman-\(\alpha \) emission at 121.6 nm. Some unexplained differences in line ratios between 130.5 nm and 147.5 nm are observed.

紧凑型SOLSTICE (CSOL)实验的太阳辐照光谱:仪器设计、FUV校准、测量和2018年火箭飞行的比较

紧凑型SOLSTICE是一种紧凑型中、远紫外(FUV和MUV)光谱仪，于2018年6月18日在探空火箭上飞行，用于验证和校准太阳辐射气候实验(SORCE)航天器上的太阳恒星辐照度比较实验(SOLSTICE)。本文报道了该仪器的设计、FUV通道的标定和FUV辐照度的测量。将辐照度测量值与SOLSTICE进行比较，在大多数波长(包括121.6 nm的H Lyman- \(\alpha \)发射)的综合仪器不确定度内显示一致。在130.5 nm和147.5 nm之间观察到一些无法解释的线比差异。

期刊介绍： Solar Physics was founded in 1967 and is the principal journal for the publication of the results of fundamental research on the Sun. The journal treats all aspects of solar physics, ranging from the internal structure of the Sun and its evolution to the outer corona and solar wind in interplanetary space. Papers on solar-terrestrial physics and on stellar research are also published when their results have a direct bearing on our understanding of the Sun.
