The Solar Ultraviolet Magnetograph Investigation: Polarization Properties

摘要

This paper describes the objectives of the Marshall Space Flight Center (MSFC) Solar Ultraviolet Magnetograph Investigation (SUMI) and the optical components that have been developed to meet those objectives. A sounding rocket payload is being developed to test the feasibility of magnetic-field measurements in the Sun's transition region. The optics have been optimized for simultaneous measurements of two magnetic lines formed in the transition region (C iv 1550 A and Mg II 2800 A). Finally, we illustrate the polarization properties of the SUMI polarimeter and toroidal variable-line-space gratings.
