Abstract

The Scientific Experimental system in Near SpacE (SENSE) consists of different types of instruments that will be installed on a balloon-based platform to characterize near-space environmental parameters. As one of the main scientific payloads, the middle and near ultraviolet spectrograph (MN-UVS) will provide full spectra coverage from middle ultraviolet (MUV, 200 nm-300 nm) to near ultraviolet (NUV, 300 nm-400 nm) with a spectral resolution of 2 nm. Its primary mission is to acquire data regarding the UV radiation background of the upper atmosphere. The MN-UVS is made up of six primary components: a fore-optical module, an imaging grating module, a UV intensified focal plane module, a titanium alloy frame, a spectrometer control module, and a data processing module. This paper presents in detail the engineering design of each functional unit of the MN-UVS, as well as the instrument’s radiometric calibration, wavelength calibration, impact test, and low-pressure discharge test. Furthermore, we are able to report ground test and flight test results of high quality, showing that the MN-UVS has a promising future in upcoming near-space applications.

近空间科学实验系统中、近紫外光谱仪(SENSE)
近空间科学实验系统(SENSE)由不同类型的仪器组成,这些仪器将安装在一个基于气球的平台上,以表征近空间环境参数。作为主要的科学载荷之一,中紫外和近紫外光谱仪(MN-UVS)将提供从中紫外(MUV, 200 nm-300 nm)到近紫外(NUV, 300 nm-400 nm)的全光谱覆盖,光谱分辨率为2 nm。它的主要任务是获取有关高层大气紫外线辐射背景的数据。MN-UVS由六个主要部件组成:前光模块、成像光栅模块、UV增强焦平面模块、钛合金框架、光谱仪控制模块和数据处理模块。本文详细介绍了MN-UVS各功能单元的工程设计,以及仪器的辐射定标、波长定标、冲击试验和低压放电试验。此外,我们能够报告高质量的地面测试和飞行测试结果,表明MN-UVS在即将到来的近空间应用中具有广阔的前景。
