Spectral calibration of the MSFC Solar Ultraviolet Magnetograph

摘要

This paper describes the scientific goals of a sounding rocket program called the Solar Ultraviolet Magnetograph Investigation (SUMI), presents a brief description of the optics that were developed to meet those goals and discusses the spectral, spatial and polarization characteristics of SUMI's Toroidal Variable-Line-Space (TVLS) gratings, which are critical to SUMI's measurements of the magnetic field in the Sun's transition region.
